Answer:

Keystone species

Explanation:

Keystone species are such species that had a large effect on the natural environment. Such species are very important species as they play key role in determining and maintaining the the structure of an ecosystem and also decide or fix which type of species will be there in that environment and what will be the number of those species in that particular community. Without these keystone species an ecosystem could completely cease or all species could not work in that same manner all-together. Wolf is one of an important keystone species in the ecosystem.
