Explanation: for the boyzzz bby
Bog freshwater ecosystem is least productive, because of its stability, or should we say stagnant variety, the freshwater bog ecosystem is the least productive, hence option C is correct.
What is freshwater ecosystem?Aquatic habitats on Earth are divided into freshwater ecosystems. They consist of marshes, rivers, streams, lakes, ponds, rivers, streams, and wetlands.
They can be compared to marine environments, which contain more salt than terrestrial ecosystems.
The least fruitful environment is the “bog freshwater” ecosystem. This form of ecosystem includes evergreen trees, shrubs, and shrubbery as well as a floor that is covered in a thick layer of sphagnum moss.
Therefore, bog freshwater ecosystem is the least productive.

Scientist who study climate changes are concerned that global warming may increase the frequency or intensity of tropical cyclones. What predicted effect of global warming would increase the destructive power of hurricans?
Global warming and hurricanes
Explanation:
Global warming and climate change lead to erratic and more destructive patterns in natural disasters like hurricanes.
Increasing global temperature has also increased the frequency of highly devastating major hurricanes. The major hurricanes which occurred once in many years or even once in a century, now occurs very frequently like once in a decade or less.
Global warming increases the sea surface temperature which in turn increases the sea level. This piling of water leads to storm surges along coastal lands.
With increasing sea surface temperature and high humidity, increases the hurricane intensity. Further, increased temperature leads to high wind at varying altitude over the sea surfaces which causes vertical wind shear that can worsen the hurricane effects.
The predicted effect of global warming would increase the destructive power of hurricanes is that warmer sea surface temperatures intensifies tropical storm wind speeds.
What is Global warming?This is defined as long-term heating of Earth's climate system sa result of the release of greenhouse gases.
This causes sea temperature to increase which brings about an increase in the intensity of tropical storm wind speeds.

Which factors are used to characterize a biome, such as the desert, tropical rain forest, or temperate grasslands? Select all of the answers that apply.
Answer:
Temperature and precipitation
Explanation:
Biomes are characterized based on dominant vegetation types in regions with similar climatic conditions. Key factors in shaping biomes include temperature and precipitation. These conditions influence the composition of plant and animal communities, and the concept applies to both terrestrial and aquatic biomes.
Explanation:
The biome, a large-scale community of organisms, is primarily characterized based on the dominant plant types that exist in geographic regions with similar climatic conditions. The Earth showcases both terrestrial and aquatic biomes. The eight major terrestrial biomes include tropical wet forests, savannas, subtropical deserts, chaparral, temperate grasslands, temperate forests, boreal forests, and Arctic tundra.
Temperature and precipitation, and variations in both of these abiotic factors, are key in shaping the composition of animal and plant communities in these biomes. For instance, biomes like temperate grasslands and forests have distinct seasons, experiencing both cold and hot weather throughout the year. In contrast, biomes such as the desert and tundra have low primary productivity due to harsh temperatures and scarcity of water.
Different vegetation and animal life can exist in geographically distinct areas with similar climates due to these factors. Apart from terrestrial biomes, there are also the aquatic biomes which include both saltwater and freshwater ecosystems, with their structuring influenced by different abiotic factors such as sunlight, density, and temperature.

Use the drop-down menus to answer each question about rock formation.
Which type of rock is formed from molten materials?
Which type of rock needs weathering or erosion to form?
The type of rock that is formed from molten materials is known as igneous rock. While the type of rock that needs weathering or erosion to form is known as sedimentary rock.
What is Weathering?Weathering may be defined as a process through which numerous rocks and minerals found on the earth's surface are considerably broken down into smaller fragments. The process of weathering is facilitated by different components like water, wind, ice, etc.
On the other hand, Erosion is different from weathering. This is because erosion deals with the transportation of broken substances or materials through weathering from one place to another with the help of air and water.
It is the gradual destruction and elimination of rock or soil in a particular area. The sedimentary rocks evolved from the activities of erosion and weathering.
Therefore, igneous rocks are formed from molten materials, and sedimentary rocks are formed from weathering or erosion.

50% of offspring will have attached earlobes as shown in the given Punnett Square. So, the correct option is B.
What is Punnett Square?Punnett square is indeed a graphical representation of the potential genotypes of an offspring that results from a certain mating event. The genetic make-up of the parents must be known in order to construct this graphical representation.
This square-shaped graphic is used to predict genotypes in breeding or cross experiments. In 1905, Reginald C. Punnett invented this method. This is used by biologists to determine the probability that a specialized gene will be passed on to progeny.
According to the Punnett Square, 50% of the offspring in the case above will have attached earlobes.

Researchers studied a typical hardwood forest containing a variety of trees, other plant species, fungi, and animals. The atmospheric carbon dioxide concentrations around the forest were measured in the middle of the day. The carbon dioxide concentration was lowest right next to the forest and steadily increased as the researchers measured farther away from the forest. Explain how this observation supports the Law of Conservation of Mass.
Group of answer choices
The carbon released by animals through cellular respiration is used by the trees to create food necessary for growth and maintenance
The carbon released into the atmosphere by decaying organic matter is increases as you move further away from the forest.
The carbon released by plants through photosynthesis is quickly cycled through the cellular respiration of animals.
The amount of carbon burned by fossil fuels decreases further away from the forest.
Answer:
The carbon released by animals through cellular respiration is used by the trees to create food necessary for growth and maintenance.
Explanation:
Since the trees are using the Carbon to grow they end up absorbing most of it therefore the levels of carbon on the forest are a lot smaller in quantities.
During the process of respiration, carbon is released by animals which is used by the trees in the process of photosynthesis to produce food for itself.
The carbon released by animals through the process of cellular respiration is used by the trees in order to create food that is necessary for growth and maintenance of the plant itself and for other organisms living in that ecosystem.
In this way the plants clean the environment and reduces the concentration of carbondioxide gas in the environment so we can conclude that carbon that is produced by the animals can be used by the other organism for itself supports the law of conservation of mass.
