Keystone species are species
whose roles have a large effect on the types and abundance of other species in
an ecosystem. Keystone species are important in the ecosystem as they help to
determine the whole ecosystem and without them, the ecosystem would be different
or stop to be in existence. Almost all animals that have a significant impact
on the food webs are examples of keystone species.
