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.

variation is useful for the survival of a species even in adverse environmental conditions. This happens as follows:
there may be some drastic changes like excessive heat or cold or shortage of water (drought) in the habitat of a species of organism . now, if all the organism 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 variation are present in some individual organism to tolerate excessive heat or cold then there are chances for them to survive .
