Answer the following:
1. A predatory wasp that feeds exclusively on herbivorous ants would be an example of a(n) _______ that is part of the _______ trophic level.
A) carnivore; third
B) herbivore; second
C) carnivore; second
D) omnivore; third
2. If herbivores eat 200 kg of plants, and the total plant biomass is 1,000 kg, the _______ efficiency is _______%.
A) assimilation; 80
B) consumption; 20
C) consumption; 80
D) assimilation; 20
3. Suppose two agents are introduced into soil: one that results in an increase in nitrification and another that results in an equal addition of denitrification. Compared to the soil before, the combination of equal amounts of nitrification and denitrification in the soil would result in a net increase in (hint â look at the reactants and the products)
A) NH4+
B) NO3â
C) N2O
1. A) carnivore; third
The trophic levels are divided by the manner in which the energy is produced and consumed among the living organisms. The first trophic level is occupied by the autotrophs, which are the organisms that are able to produce their own food. The second trophic level is occupied by the organisms that feed upon the autotrophs, thus they are the herbivores, as well as the omnivores in partial sense. In this case we will have the ants at the second level. The third trophic level is reserved for the organisms that feed upon the organisms of the second trophic level, thus they are predators. In this case, we will have the wasp in the third trophic level.
2. B) consumption; 20
If there are herbivores and plants, the plants account for 1,000 kg in biomass, and the herbivores eat 200 kg of them, then the consumption is 20% of the total biomass. This kind of a scenario is able to support the whole population of herbivores without any problem, as there is much more food than they need. It will only become a problem if the population of herbivores starts to grow exponentially, and they start to consume all of the food and even require more, the population will collapse.
3. C) N20
The processes and nitrification and denitrification are very common, both in nature, and because of the human activity. The human activity has actually increased this process significantly. The main product of the nitrification-denitrification is the N2O. It is a vital product for the nitrogen cycle, and it is one that is increasing the atmospheric temperature, thus too much of it is not of best interest for anyone.

Milankovitch cycles refer to
changes in Earth-Sun relationships, namely Earth's orbit around the sun, axial rotation, and axial tilt.
topographic changes from orogeny, erosion, and mass movement.
cyclical changes in solar irradiance caused by increases and decreases in sunspot activity.
increases and decreases in atmospheric gases and aerosols, primarily caused by natural activity, such as volcanic eruptions and changes in net primary productivity.
tectonic changes in continental positions
Milankovitch cycles refer to changes in the Earth-Sun relationships caused by variations in the Earth's orbit, axial rotation, and axial tilt, affecting the climate and leading to cycles of ice ages and warm periods.
Explanation:Milankovitch cycles refer to changes in Earth-Sun relationships, which are specifically caused by variations in the Earth's orbit around the sun, axial rotation, and axial tilt. These changes lead to long-term alterations in the sunlight Earth receives, affecting climate over thousands of years. For example, the axial tilt changes over around 41,000 years from 22.1 to 24.5 degrees and back. When the tilt increases, summers get warmer and winters colder, contributing to the start and end of ice ages. However, they do not refer to topographic changes, solar irradiance changes due to sunspot activity, or changes in atmospheric gases and aerosols. The concept of Milankovitch cycles is primarily used in the field of paleoclimatology.

Milankovitch cycles refer to changes in Earth's relationships with the sun, including Earth's orbit, axial tilt, and axial rotation. These changes, derived from the theory developed by Milutin Milankovitch, result in long-term climate variations on Earth.
Explanation:The Milankovitch cycles primarily refer to the changes in Earth-Sun relationships that include Earth's rotation, axial tilt, and the shape of its orbit around the sun. Serbian engineer and mathematician Milutin Milankovitch developed this theory, which explains long-term climate changes on Earth. His theory is based on three parameters: Eccentricity, Obliquity, and Precession. Eccentricity is the variation in the shape of Earth's orbit from nearly circular to elliptical over about 100,000 years. Obliquity pertains to the change in axial tilt over around 41,000 years, and Precession refers to the gradual shift in the direction of Earth's axial rotation over roughly 26,000 years. Together, these parameters resulting in Milankovitch cycles are thought to be a significant driver of Earth's long-term climate variability.

Why doesn’t radiometric dating of basalt on the ocean floor provide us with an absolute age for the planet earth?
Select one:
a. New oceanic crust is produced every day
b. Black smokers alter the rock so radiometric dating is ineffective
c. Spreading rates at mid-oceanic ridges are variable
d. Oceanic crust is recycled too frequently at subduction zones
e. Mid-oceanic ridges move over time
Answer:
Why doesn’t radiometric dating of basalt on the ocean floor provide us with an absolute age for the planet earth -
Oceanic crust is recycled too frequently at subduction zones,
Explanation:
The reason why radiometric dating of basalt don’t give the exact age of the sea floor because the oceanic crust is denser in nature and at the subduction zone this oceanic crust subducts under the light continental crust where it melts and thus recycling of oceanic crust takes place very frequently and hence it cannot be used for absolute dating of the oceanic crust and therefore the correct option is option ( d ) Oceanic crust is recycled too frequently at subduction zones .
Radiometric dating of basalt on the ocean floor cannot give an absolute age for Earth due to the continuous production of new oceanic crust and the recycling of crust at subduction zones. So, option a is correct.
The reason radiometric dating of basalt on the ocean floor does not provide an absolute age for the planet Earth is because that new oceanic crust is produced every day. This continuous generation of new crust makes it challenging to obtain a definitive age for the planet through radiometric dating of basalt in oceanic regions. Additionally, oceanic crust is recycled too frequently at subduction zones, further complicating the determination of Earth's absolute age using this method.

the movement of water within the surf zone that parallels the shore is called ----------------
The movement of water parallel to the shore within the surf zone is known as longshore current, which, along with the associated sediment movement called longshore drift, plays a key role in coastline shaping.
The movement of water within the surf zone that parallels the shore is called longshore current. This current is generated by waves that approach the shoreline at an angle, causing the water to move along the shore as they break in the surf zone.
The process by which this motion results in the movement of sediments, such as sand, along the coast is known as longshore drift. These processes play a crucial role in shaping coastlines and creating various coastal features like spits and baymouth bars.
The longshore drift is responsible for the transport of a significant amount of sediment along coasts worldwide, which can lead to the development of specific depositional landforms.

Answer:
The correct option here is B) differential in power.
Explanation:
As per the Noel hypothesis Africans were chosen above other groups such as native Americans and other white groups because of differential in power . The whites had a more dominant position than the Africans, who were brought in to the country as cheap labor. According to this hypothesis if a couple of groups come together who were characterized by the features such as ethnocentrism, competition and differential in power , then this will lead to a racial stratification.

Which of these statements or sentences best describe "The Migratory Bird Rule". Select one a. was promulgated by the EPA. b. prohibits hunters from shooting birds that migrate across states. c. was struck down by the Supreme Court in the late 1990s or early 2000. d. allows bird watchers to sue persons who kill or poison birds.
Answer:
c. was struck down by the Supreme Court in the late 1990s or early 2000.
Explanation:
The correct answer is option B.The best statement describing 'The Migratory Bird Rule' is the prohibitive measure against hunters targeting migratory birds crossing state lines, guided by the Migratory Bird Treaty Act of 1918. The law is crucial for the conservation of over 800 bird species, but has faced recent challenges limiting its scope to only intentional harm.
The Migratory Bird Treaty Act (MBTA) is a cornerstone of wildlife conservation law in the United States, having been enacted in 1918 in conjunction with Canada to address the decline of bird species due to hunting pressures. The statement that best describes 'The Migratory Bird Rule' is the one that refers to the prohibition of hunters from shooting birds that migrate across state lines. This legislation makes it illegal to hunt, disturb, or kill over 800 protected migratory bird species, such as the northern cardinal or the American black vulture.The MBTA was originally established to halt the declines in bird populations by making it unlawful to bother or kill protected species or to trade their parts, a practice that was once quite common for their feathers. The act is notable for allowing regulated hunting under certain conditions but also for setting stringent protections against the deaths caused by industrial activities, such as those resulting from oil spills or mining operations. However, recent administrative revisions have focused on the 'incidental take' provision, which has now been interpreted to not apply unless intentional harm can be demonstrated, thus potentially weakening the principal protections of the MBTA.
clues to the nature of the source area of sediment can be found in
Clues to the source area of sediment include its mineral composition, fossil content, and textural features such as sorting and rounding. These clues help determine the provenance, which is key for understanding geological history and past climates.
Clues to the nature of the source area of sediment can often be found by analyzing certain characteristics of the sediment itself. For example, the mineral composition, fossil content, and textural features such as sorting and rounding, can help scientists to determine the provenance of the sediment. This is essential for understanding the tectonic history, visualizing paleogeographic formations, and unraveling geological histories. Sedimentology is a specific tool used to investigate past environments and climates by examining the size, shape, texture, and composition of sediment deposits.
For instance, biotite grains found at the bottom of a lake could indicate that they originated from nearby metamorphic rocks or granites, depending on their ages and the geology of the area. Additionally, different environments of deposition are indicated by the characteristics of the sedimentary rocks formed. For example, a quartz sandstone with well-sorted and well-rounded grains suggests long-distance transportation by water, while a breccia with poorly sorted, angular limestone fragments indicates deposition closer to the source rock.

List five processes by which rocks can change from one form to another?
Answer:
The five process bu which rocks can change from one form to another are -
1. Weathering 2. Metamorphism 3. Cooling and crystallization 4. Lithification of sediments 5. Igneous rocks change into metamorphic rocks
Explanation:
The processes by which rocks can change from one form to another are as follows :
1. Weathering : It wears/breaks down the rocks at the surface of Earth’s into smaller pieces.
2. Metamorphism : This changes the entire texture as well as the mineral composition of the rock under conditions of extremely high temperature and pressure.
3. Cooling and crystallization from a molten magma material results in the generation of igneous rocks.
4. Lithification of sediments with proper compaction and cementation leads to the formation of consolidated sedimentary rocks.
5. Igneous rocks change into metamorphic rocks when subjected to high temperature and pressure conditions deep inside the Earth.
2. If both the mass and radius of the earth, each decreases by 50%, the acceleration due to gravity would (a) remain same (b) decrease by 50% (c) decrease by 100% (d) increase by 100%
Answer:
(d) increase by 100%
Explanation:
[tex]m_{i}[/tex] = initial mass of earth = m
[tex]m_{f}[/tex] = final mass of earth = (0.5) m
[tex]R_{i}[/tex] = initial radius of earth = R
[tex]R_{f}[/tex] = final radius of earth = (0.5) R
[tex]g_{i}[/tex] = initial acceleration due to gravity of earth = g
[tex]g_{f}[/tex] = final acceleration due to gravity of earth
initial acceleration due to gravity of earth is given as
[tex]g_{i} = \frac{Gm_{i}}{R_{i}^{2}}[/tex] Eq-1
Final acceleration due to gravity of earth is given as
[tex]g_{f} = \frac{Gm_{f}}{R_{f}^{2}}[/tex] Eq-2
Dividing eq-1 by eq-2
[tex]\frac{g_{i}}{g_{f}} = \frac{m_{i}}{m_{f}}\frac{R_{f}^{2}}{R_{i}^{2}}[/tex]
inserting the values
[tex]\frac{g}{g_{f}} = \frac{m_{i}}{(0.5)m_{i}}\frac{(0.5)^{2}R_{i}^{2}}{R_{i}^{2}}[/tex]
[tex]g_{f}[/tex] = 2 g
So there is 100% increase

b. Building Construction
c. Road construction
d. Agriculture
Question 44
Which type of sediment deposit can fail and lead to a mass wasting event when the amount of water is decreased between the grains?
Select one:
a. boulders
b. silt
c. clay
d. sand
Answer 40: d. Water lowers strength and cohesion.
Explanation: The most ideal approach to comprehend this is by taking clayey soil and adding water to it. You will see that earth without water is an intense week with great quality. On the off chance that you add water to the blend, the dirt will have lower straight however it by hitting it with the mallet, it will really be somewhat moldable. Along these lines the quality of the strength and cohesion will get lower with lack of water.
Answer 41: a. The soil expands and contracts, lifting particles and dropping them a slight distance downslope.
Explanation: Creep, in geography, slow downslope development of particles that happens on each slant secured with free, endured material. Indeed, even soil secured with affectionate turf creeps downslope, as demonstrated by moderate however determined tilting of trees, shafts, tombstones, and different articles set into the ground on slopes. So the dirt extends and contracts, lifting particles and dropping them a slight separation downslope.
Answer 42: c. The geological age of the rocks.
Explanation: Mass squandering happens when the dirt/shake particles that are endured can't be held together and along these lines slide down the outside of an edge. In this way power because of gravity pull the unconsolidated issue down the slant. The measure of water in connection to the stone/soil substance adds to this. Free shake particles will slide effectively because of water. Dirt ingests the water somewhat however in abundance can surrender. The point of the slop chooses how quick squandering can happen. A precarious incline will cause mass squandering effectively when contrasted with a delicate slant.
Answer 43: c. Road contraction
Explanation: Road compression is the most widely recognized explanation behind mass squandering. Most street development takes puts by slicing through the bedrock-leaving the newly cut roadway uncovered. On the off chance that there is a blamed territory or region that isn't well-vegetated or essentially bedrock strata with a lofty incline, mass squandering can happen. To maintain a strategic distance from this, joining is normally done which incorporates fixing the newly cut shake body surface.
Answer 44: d. sand
Explanation: The definition is "an immersed soil mass moving by liquidity down a slant" in light of the fact that "a soaked soil mass" is certifiably not a fluid. Note that both mudflows and avalanches are made out of shake, earth, and garbage. The contrast in the measure of water they contain.
The strength and cohesion of clay-rich soil decrease with water addition, contributing to mass wasting. Freezing, thawing, wetting, and drying lead to soil creep, and factors like gravity, water content, slope angle, and anthropogenic changes like road construction affect mass wasting. Geologic age of rocks doesn't affect mass wasting, and sand is susceptible to failure when it dries out.
The addition of water to clay-rich regolith or soil generally lowers both the strength and cohesion of the material, making the correct answer (d) Water lowers strength and cohesion. For the question of how freezing, thawing, wetting, and drying contribute to soil creep, they cause the soil to expand and contract, which lifts particles and drops them downslope, thus (a) The soil expands and contracts, lifting particles and dropping them a slight distance downslope is correct. Factors affecting mass wasting include gravity, water content, and the slope angle. The geologic age of rocks does not directly affect mass wasting, making (c) geologic age of rocks the correct choice for the unrelated factor. The most common anthropogenic cause of mass wasting is (c) Road construction, as it can alter landscapes significantly. Lastly, when the amount of water decreases between the grains, sand deposits can fail and lead to mass wasting events, which makes (d) sand the right choice.
