Question

variation is beneficial to the species but not necessarily for the individual give three reason to justify it​

Answer 1

Answer: Variations are beneficial to the species than individual because sometimes for a species, the environmental conditions change so drastically that their survival becomes difficult. ... However, all variations are not necessarily beneficial for the individual organisms.

Answer 2

Variations are the changes that occur in the organisms. These variations may give the species survival advantage.

For eg.

Due to certain variations some bacteria became resistant to heat and survived even when there was a rise in temperatue because of the heat wave,while the other bacteria which did not have this variation died.

So here the resistance to heat ensured the survival of some of the organisms and prevented the species from getting extinct.
