Question

define variation in relation to a species. Why is variation beneficial to the species?

Answer 1

Variations are differences in individuals of same species
Variations provided adaptation to adverse conditions so they are beneficial for organisms....

Answer 2

Explanation:

Variations are beneficial to the species than individual because sometimes for a species, the environmental conditions change so drastically that their survival becomes difficult. For example, if the temperature of water increases suddenly, then most of the bacteria living in that water would die. Only few variants that are resistant to heat would be able to survive. However, if these variants were not there, then the entire species of bacteria would have been destroyed. Thus, these variants help in the survival of the species. However, all variations are not necessarily beneficial for the individual organisms.
