Question

Quizplus · Accepted Answer

A study conducted a decade after the reintroduction of wolves to Yellowstone Park found that the presence of wolves had led to changes in the behavior of elk, their primary prey. The elk had become more vigilant and avoided areas where they could be easily targeted by wolves, leading to a decrease in browsing pressure on plants and trees in certain areas of the park. This, in turn, allowed for the regeneration of vegetation and the return of other wildlife to the area. Therefore, the correct answer is C, that the reintroduction of wolves had changed the behavior of elk.
