Question

How does the creation of variation in a species ensure its survival?

Answer 1

Answer:

It ensures better survival of species.

Explanation:

Due to some uncertain natural calamities a species may get completely destroyed.For example take a group of bacteria which lives in water.It can with stand only certain temperature.And due to global warming the whole species may get extinct if there are no variants . But if there are a few variants which are resistant to heat then the species may survive.Thus it ensures better survival of species.

Answer 2

Answer:

Here's your answer:

Variation is useful for the survival of species even in the adverse environments like in excessive heat or cold or even shortage of water.

Now, if all the organisms of a species are exactly identical then there is a danger that no one would survive under the adverse conditions. This will eliminate the species completely. However, if some variations are present in some individuals to tolerate the excessive heat or cold then there is a chance for them to survive in the adverse environment.

Hence, variations are important for the survival of species.
