Question

Quizplus · Accepted Answer

Keystone species are species that have a disproportionate impact on their ecosystem relative to their abundance. They play a critical role in maintaining the structure and function of the ecosystem. If a keystone species is removed, the entire ecosystem can change dramatically. Dominant species, on the other hand, are simply the most abundant species in an ecosystem and may not necessarily have a disproportionate impact on the ecosystem. Endangered species are those that are at risk of extinction, while natural species is not a recognized biological term.
