Answer
When a keystone species is removed from a community, it can cause the extinction of other species. This extinction happens because the keystone species reduces competition, allowing more species to coexist on a resource, thereby maintaining diversity. When the keystone species is gone, the resource competition goes up, and the species that can't compete as effectively will go extinct.
