Question

what is a keystone species

Answer 1

A keystone species is a species that plays a critical role in maintaining the structure and function of an ecosystem. They have a disproportionately large impact on their environment relative to their abundance, and their presence is crucial for the overall health and stability of the ecosystem. If a keystone species is removed, it can have far-reaching effects on other species and the ecosystem as a whole. Examples of keystone species include predators that control prey populations, such as sea otters in kelp forests and wolves in Yellowstone National Park.
