Answer

Brief Explanations:

A keystone species has a disproportionately large impact on its ecosystem relative to its abundance. It helps maintain the structure and function of the ecosystem. Genetic variation, population size, immunity to environmental changes, or being the first - colonizing species are not the defining characteristics of a keystone species.
