What would happen if rats was eliminated from the environment

1 answer:

3 0

Rats account for a decent amount of biomass globally. They are intermediate predators, eating a lot but also being eaten. If they went extinct, they would stop eating many insects and seeds / fruits -- the former would gain significantly in population, and the latter would lose some of their pollination. Both factors would harm the viability of at least some species of plants, by adding to plant eaters (insects) and reducing plant reproduction. Rats' predators would also suffer if they went extinct. The primary predators are birds of prey, such as hawks and owls. However, other animals such as skunks, foxes, weasels, coyotes, and even wolves eat rats. For predators in marginal environments, the loss of such a food source could drive them out of a habitat area.

Are the layers of rock above and below the coal older or younger?

son4ous [18]

<u>Answer:</u>

The layer of the rock is older than the layer above it and younger than the layer below it.

<u>Explanation:</u>

According to the law of superposition, the layer which is above is always younger than the layer below it. This law is based on the very common fact that the older layer had to lay down first and then a new layer formed above it. This process is used to determine the relative age of the rocks.

once genetic isolation separates two populations from each other, genetic divergence begins to happen as a result of the process

Yanka [14]

Once genetic genetic isolation separates two populations from each other, genetic divergence begins to happen as a result of the processes of genetic drift, mutation, and natural selection. The process which is more likely to be the slowest is mutation.

<h3>What is mutation ?</h3>

A mutation is a change to an organism's DNA sequence. Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations.

<h3>What is genetic drift ?</h3>

Genetic drift is an evolutionary process in which the frequency of a given gene allele varies randomly across a population.

<h3>What is natural selection ?</h3>

An evolutionary mechanism is natural selection. Environment-adapted organisms have a higher chance of surviving and dispersing the genes that contributed to their success. Over time, this mechanism leads to the evolution and divergence of species.

Thus from above conclusion we can say that once genetic genetic isolation separates two populations from each other, genetic divergence begins to happen as a result of the processes of genetic drift, mutation, and natural selection. The process which is more likely to be the slowest is mutation.
