Why is it necessary for there to be variation in population in order for evolution by natural selection to occur?

Answers

Answer:

There needs to be variations in population in order for natural selection to occur because the entire point of evolution by natural selection is only the best variations will survive. So if there were no variations then there would be no natural selection because the animal's survival rate would be the same no matter how many times they reproduce because there are no different variations being introduced into the species. However, if there are variations then the animal's survival rate could be impacted because of the variations, for example, white mice would be easier to find for predators on a dark surface, while a darker mice would be harder to find for predators on a dark surface, thus, allowing the darker mice to prevail as they have a higher survival rate and the species will slowly evolve into the darker mice. But, if there were no evolution, in this case, then no matter what happens, the white mice would not be able to evolve into a darker mice because there are no such thing as variation. That is why it is necessary for there to be variation in order for evolution by natural selection to occur.

How does the carbon stored in the bodies of living organisms move into rocks?(1 point)

Carbon dioxide released through respiration dissolves in certain rocks, like limestone.

Living organisms decay, releasing carbon into the soil, and soil is compacted into rocks.

Living organisms decay and become fossils fuels, which eventually become rocks.

Carbon dioxide dissolves in ocean water and is slowly absorbed by rocks in the ocean.

Answers

In the atmosphere, carbon is stored in the form of gases, such as carbon dioxide. ... This carbon can then be ingested and stored in animals that eat the plants. When the animals die, they decompose, and their remains become sediment, trapping the stored carbon in layers that eventually turn into rock or minerals.

When animals die, their bodies degrade into the soil, encasing the carbon in layers that eventually transform into rock or minerals. hence option b is correct.

What is rock?

Stone including limestone and its minerals is created when sediment and shell layers are bonded together over time.

Gases like carbon dioxide are among the forms of carbon that are stored in the atmosphere. Animals that consume the plants can then absorb and store this carbon.

When animals die, their bodies degrade into silt, encasing the carbon in layers that eventually transform into rock or minerals. Some of this silt may eventually turn into fossil fuels like coal, oil, or natural gas, which when burned, release carbon back into the atmosphere.

Therefore, when an animal dies to decompose into the soil which becomes rocks through carbon from living organisms moves into rocks, hence option b is correct.
