When an organism from one trophic level of a food chain is eaten by the organism at the next level up the chain, an average of about 10% of the energy from the first organism is available for use by the next organism. Where does the other 90% go at each level?
Answer:
The 90 % of energy is released in the ecosystem in the form of heat.
Explanation:
In each trophic levels of ecosystem, 90 percent of energy is lost as heat energy in the ecosystem while only 10 percent of energy is transferred from one trophic level to the next trophic level and becomes a part of that organism. For example, plants are the producer having 5000 kcal energy. When these plants are eaten by primary consumer such as cow, rabbit etc, about 500 kcal of energy is transferred to primary consumer and the rest of it is lost as heat energy.
The other 90% of the energy at each level of the food chain is lost to the environment, primarily through metabolic processes, heat loss, and waste products.
In ecology, the transfer of energy between trophic levels is governed by the principle of energy flow through an ecosystem. When energy enters the ecosystem through producers (usually plants), it is captured through photosynthesis. However, as energy moves through each trophic level, a significant amount is lost and is not available to the next level.
Here's a breakdown of where the energy goes:
1. Metabolic Processes: Organisms use energy for their life processes, such as respiration, digestion, and movement. Much of the ingested energy is used to maintain basic body functions and is lost as heat.
2. Heat Loss: The second law of thermodynamics states that in any energy exchange, if no energy enters or leaves the system, the potential energy of the state will always be less than that of the initial state. This essentially means that some energy is always transformed into heat and dissipated into the environment.
3. Waste Products: Not all parts of the organism are digestible. Some energy is lost in the form of feces and other waste products that are not consumed by the predator.
4. Undigested Parts: Some parts of the prey may not be consumed at all, such as bones, fur, or shells.
5. Growth and Reproduction: Some energy is invested in growth and the production of offspring, which may not be directly available to the predator.
The 10% rule is a simplification and the actual percentage can vary. Some ecosystems may have more efficient energy transfer, but generally, only about 10% of the energy is available to the next trophic level. This inefficiency in energy transfer limits the number of trophic levels in a food chain, typically to four or five. This limitation is known as the trophic pyramid of energy, with the largest amount of energy at the bottom (producers) and successively smaller amounts at each higher trophic level.

How could the situation in Haiti be improved?
Answer:
Billions of dollars of foreign aid has poured into Haiti with little to show for it. This is largely because that money has come to do for Haitians what, with a little help in expertise, they could have done for themselves. This is the biggest difference between aid and development. As a result, 74% of Haitians are either unemployed or under-employed and 8.5 million live on less than $2.41 per day.
Aid is designed to help with immediate needs. As important as that is at times, aid is not the solution to Haiti’s long term challenges. The Haitian people are the solution to Haiti’s problems, particularly those who have the skills and character to build a stronger Haiti for all.
By helping men and women gain the skills to build, train, and lead, you have the power to unleash Haiti’s potential to create a stronger future. Through Extollo’s unique approach to development you will help build stronger careers, stronger families, stronger communities, and a stronger infrastructure for all Haitians.

Swedish scientist Carl Linnaeus is known for creating the first version of the modern taxonomy system in the 1700s. Which of the following is NOT a classification in the Linnaean system of naming?A:Genus B:Species C:Class D:Prokaryote
Answer:
D. Prokaryote
Explanation:
The Linnaean system of naming consists of domain, kingdom, phylum, class, order, family, genus, and species. I remember it with "D- King Phillip Came Over For Great Soup".
I hope this helps!
Final answer:
The classification 'Prokaryote' is NOT part of the Linnaean system of naming; Carl Linnaeus's system includes Genus, Species, and Class among other ranks.
Explanation:
Swedish scientist Carl Linnaeus is renowned for creating the first comprehensive taxonomy system in the 1700s, which is crucial for the science of taxonomy, the classification and naming of organisms. The Linnaean system includes a hierarchical structure with several levels of classification, including Kingdom, Phylum, Class, Order, Family, Genus, and Species. Notably, Linnaeus is responsible for introducing binomial nomenclature, where each species is given a two-word name, with the first word indicating the genus and the second the species itself.
The correct answer to the student's question is D: Prokaryote. This term refers to a broad grouping of organisms that do not have a nucleus, which falls outside the hierarchical ranks established by Linnaeus. Instead, the classifications within the Linnaean system are Genus, Species, and Class, making Prokaryote the classification not part of the Linnaean system of naming.

Which of the following happens at mid-ocean ridges and is essential for the process of plate tectonics being able to continue?
A). Old rock is melted into magma.
B). New rock is formed from magma.
C). Seamounts are shaped.
D). Trenches are destroyed.
At mid-ocean ridges, new rock is formed from magma, which is essential for plate tectonics to continue.
Explanation:Mid-ocean ridges play a vital role in the dynamic process of plate tectonics. These underwater mountain ranges are located at divergent boundaries, where tectonic plates are moving apart from each other. At these locations, new rock is formed through a process involving magma.
Magma, which is molten rock beneath the Earth's surface, rises up from the mantle to fill the gap created by the separating tectonic plates. As the magma approaches the ocean floor, it encounters lower pressure, causing it to melt and form new rock. This process is known as decompression melting. The newly formed rock solidifies upon contact with the cold seawater, creating fresh oceanic crust.
Over time, this continuous cycle of magma rising, solidifying, and forming new rock contributes to the expansion of the seafloor. As new crust is generated at mid-ocean ridges, it pushes the existing oceanic crust away from the ridge in both directions, driving the movement of tectonic plates and influencing the shape and size of Earth's continents.

1. If Mike drove for nine hours at a speed of 105km/h, how far did he drive in meters (m)?
2. Ann jogged 5.5 miles south to her house in 0.9 hours. What is Ann's speed? What is Ann's velocity?
3. How long will it take a car to accelerate from 18.9 m/s to33.7 m/s if the car has an acceleration of 4.2m/s2?
Answer:
1) 945000 m
2) 6.11 miles/hour
3) 3.52 seconds
Explanation:
1. Speed is the time rate of change of distance, it is the ratio of distance to time. Speed is given by the equation:
[tex]speed(S)=\frac{distance(d)}{time(t)}[/tex]
Given that:
Time (t) = 9 hours and Speed (S) = 105 km/h
[tex]S=\frac{d}{t}\\ d=S*t=105*9=945km=945000m[/tex]
2) Time (t) = 0.9 hours and distance (d) = 5.5 miles
[tex]S=\frac{d}{t}\\ S=\frac{5.5}{0.9} =6.11miles/hour[/tex]
3) Acceleration it is the ratio of velocity to time. Acceleration is given by the equation:
[tex]Accceleration(a)=\frac{Final,velocity(u)-initial, velocity(v)}{time(t)}[/tex]
Given that :
a = 4.2 m/s² , u = 18.9 m/s and v = 33.7 m/s
[tex]a=\frac{v-u}{t}\\ t=\frac{v-u}{a}\\ t=\frac{33.7-18.9}{4.2}=3.52s[/tex]
Answer:
1) 945.000 meters
2) 9,84 kilometers/hour
3) 3,52 seconds
Explanation:
1) 105 km/h x 9 h = 945km
1km = 1000 meters 945 km = 945.000 meters
2) 1 mile = 1.61 km
5.5 miles x 1.61 km / 1 mile = 8,855 km
You have to do a single third rule to clear the x which is the Ann's velocity in 1 hour.
8,855km in 0.9 hs
x (velocity in 1 hour) = 9,84 km = 1 hs
1 hs x 8,855km / 0,9hs = 9,84km/h
v= 9,84km/h
3) you have to use this formula and clear T (time)
vf = v0 + a.t
vf-v0 = a.t
(vf - v0)/a = t
(33.7 m/s - 18.9 m/s) / 4.2 m/s2 = 3,52 seconds

After the Krebs cycle only a small portion of the energy of gluecose has been converted to atp. At this point the majority of usable energy contained in
Cellular respiration is a three-part process including glycolysis, the Krebs cycle, and electron transport chain, designed to extract energy from glucose. Only a small portion of the energy is converted to ATP after the Krebs cycle. Most of the energy is still carried by high-energy electrons sent to the electron transport chain.
Explanation:The process you're asking about is called cellular respiration and is used to extract usable energy from glucose. It is a three-part process involving glycolysis, the Krebs cycle, and the electron transport chain.
Glycolysis, which occurs in the cytoplasm of the cell, is the first stage. In this process, glucose is split into two three-carbon sugars, with the investment and subsequent production of 2 ATP per glucose molecule. Next, the Krebs cycle (or Citric Acid Cycle) takes place in the mitochondria and produces a small amount of ATP, but its main purpose is to provide high-energy electrons used in the next stage.
The electron transport chain is where most of the energy is produced. The high-energy electrons provided by the Krebs cycle are used to create a large amount of ATP as they are transported along a series of proteins. This whole process only extracts about 34 percent of the energy contained in glucose, with the rest being released as heat.
Therefore, it is correct that only a small portion of the energy of glucose has been converted to ATP after the Krebs cycle. Most of the energy is still in high-energy electrons passed on to the electron transport chain.
