Answer 1

The correct response to how the reintroduction of wolves to Yellowstone National Park affected the beaver population is:

**The wolves increased the population by eating beavers’ predators.**

This response reflects the idea that by controlling the populations of large herbivores (like elk) that graze on willow and aspen (which are important for beaver habitats), wolves indirectly benefited beavers by ensuring more food and habitat availability for them.
