Answer 1

The most likely keystone species among the options provided is wolves in Yellowstone National Park, which eat elk, who graze on willows, on which beavers depend to build their dams. Keystone species play a crucial role in maintaining the structure of an ecosystem, and in this case, wolves help regulate the elk population, which in turn affects the vegetation and the habitats of other species like beavers.
