Question

Quizplus · Accepted Answer

A keystone species is a species that has a disproportionately large impact on the community it inhabits relative to its own abundance or biomass. It plays a critical role in maintaining the structure and function of an ecosystem, often providing key resources or services that support a diverse array of other species. Without the keystone species, the community would be fundamentally altered and may even collapse. Therefore, a keystone species may make up a small portion of the community by weight, yet exerts a disproportionate influence on community diversity.
