Answer 2

The importance of variation in organism intoduced during reproduction is that it helps the species of various organisms to survive and flourish even in adverse environment. if all the organisms of a population living in that habitat are exactly identical,then there is a danger that all of them may die and no one would survive under those Conditions. this will eliminate the species from the habitat completely. however,if some variations are present in some individual organism to tolerate excessive heat or cold, then there is a chance for them to survive and flourish even in adverse excessive heat or cold. thus, variation is useful for the survival of a species over time.
