Hi friend,

Variations are important for species for their survival.This is because without variation an entire species could be wiped out by a disease, famine, or a sudden unexpected change in the environment.

Answer 2

Variations are basically for better survival .It leads to slight changes in the characteristics of the organism which makes it a better orgamism than the pre existing ones . It plays an important role in maintaining the existence of species. Eg . Consider a group of bacteria residing in a pond , suppose some hot water is discharged into it so if baterium with variations are also present which have the ability to resist high temperatures, will not be affected but the pre existing ones with no resistence will eventually die . Here variations resulted in preventing the species of bateria from being extinct .
