In a forest ecosystem, a variety of predators compete with one another for the same prey. The predators include wolves, coyotes, foxes, and hawks. Their prey include deer, rabbits, mice, and
the chickens that live outdoors on nearby farms and backyards.
Suppose that human activities, such as hunting, drastically reduce the populations of
the wolves, coyotes, and foxes. Which statement best explains a likely change to the hawk
population?
