Answer:
Variations can be beneficial or harmful according to the ecological niche of the organism.
A variation suitable for the particular niche is selected by nature in evolution. Thus, variations are necessary for the survival of the species.
Variation is important for the evolution of the species.
Variations are beneficial to the species than individuals because sometimes, survival will be difficult for a species under certain environmental conditions. For example, if the water temperature is increased suddenly, the microorganisms living in the water will die soon, and some percentage will survive due to the heat withstanding capacity. Thus, if variations are not there, all the microorganism would have been destroyed.
Example
A population of heat-resistant bacteria in the water temperature survives if the temperature of water increases by global warming, but most other bacteria would die.
