How did the reintroduction of wolves to Yellowstone National Park affect the beaver population?
The wolves decreased the population by eating beavers prey
The wolves increase the population by eating a competitor
The wolves decreased the population by eating beavers
The wolves increased the population by eating beavers predators
The correct answer is: The wolves increased the population by eating beavers' predators.
When wolves were reintroduced to Yellowstone National Park, they had a cascading effect on the ecosystem. As apex predators, wolves helped control the population of various herbivores, such as elk. This reduced the pressure on vegetation, allowing plant communities to regenerate. The increase in vegetation provided more food and habitat for beavers and other small mammals. Additionally, wolves also indirectly reduced the number of coyotes, which are predators of beavers. Therefore, the reintroduction of wolves ultimately led to an increase in the beaver population in Yellowstone National Park.
