Secondary extinction

Explanation:

Primary extinction is the disappearance of a species due to environmental impacts caused by human actions. The primary extinction of one species may result in the extinction of another species. In this case, there is talk of secondary extinction. Thus we can state that secondary extinction happens when the death of one species causes the decline or elimination of others.

The likelihood of secondary extinction will depend on a number of factors, including the characteristics of the endangered species and its interaction with the first extinct species.
