SCIENCE: BILOGICAL FACTORS.
HOW DID THE REINTRODUCTION OF WOLVES TO YELLOWSTONE NATIONAL PARK AFFECT THE BEAVER POPULATION?
1. THE WOLVE INCREASED THE POPULATION BY EATING A COMPETITOR.
2. THE WOLVES DECREASED THE POPULATION BY EATING BEAVER'S PREY.
3. THE WOLVES INCREASED THE POPULATION BY EATING BEAVER'S PREDATORS.
4. THE WOLVES DECREASED THE POPULATION BY EATING BEAVERS.
4. THE WOLVES DECREASED THE POPULATION BY EATING BEAVERS.
The reintroduction of wolves to Yellowstone National Park had a negative impact on the beaver population as wolves preyed on beavers, resulting in a decrease in their numbers. Wolves are natural predators of beavers and their reintroduction disrupted the ecosystem balance, leading to a decline in the beaver population.
