Question

why is variation important for species

Answer 1

Hey mate..
=========

First of all,

What is variation ?

Variation refers to differences among organisms of the same species due to the differences in the genes they inherit and the environment they survive .

So, Why is variation important for a species ?

Let us understand this with the help of an example :-

We know that , Reproduction is linked to the stability of the populations of the species.

If a population of organisms were suited to a particularange niche and if the niche were drastically altered, then the population will be wiped out. However, if some variations were to be present in a few individuals in this population , there would be some chance for them to survive . Thus , if there were a population of bacteria living in temperate water and if the water temperature were to be increased by Global Warming, most of the bacteria present there would die but only a few variants which are resistant to heat wold be able to survive and grow further.

That is why, Variation is important for the survival of some species over time.

Answer 2

Variation is necessary for the survival of species as variation makes species more adapted to survive with the changing environmental conditions. The variant species are more adapted to changing environment. Therefore, they can survive better and reproduce to pass the genes of the offspring.
