(02.04 MC) Scientists exаmining ecоsystems in Yellоwstоne Nаtionаl Park found that the populations of certain plant species preyed on by elk – including willow trees and cottonwood plants – had declined prior to the implementation of the Endangered Species Act and the reintroduction of gray wolves to the park. Restoring Yellowstone's wolf population caused the elk population on which the wolves prey to decrease and the willow and cottonwood populations to increase. This caused a corresponding increase in Yellowstone's beaver population, which preys on willow trees. Which species is most likely the keystone species at Yellowstone?
