Detailed explanation-1: -Without its keystone species, the ecosystem would be dramatically different or cease to exist altogether. Keystone species have low functional redundancy. This means that if the species were to disappear from the ecosystem, no other species would be able to fill its ecological niche.

Detailed explanation-2: -Keystone species hold together the complex web of relationships in an ecosystem. They can be animals, plants or microorganisms. Examples of keystone species include starfish, sea otters, wolves and elephants.

Detailed explanation-3: -What Effect Do Keystones Have on an Ecosystem? Keystone species maintain the local biodiversity of an ecosystem, influencing the abundance and type of other species in a habitat. They are nearly always a critical component of the local food web.

Detailed explanation-4: -Beaver. The American Beaver (Castor canadensis) is one example of a keystone species in North America. In any arrangement or community, the “keystone” is considered one of the most vital parts. In a marine ecosystem, or any type of ecosystem, a keystone species is an organism that helps hold the system together.
