Name 2 impacts the wolves had on the deer population at Yellowstone

1. The presence of wolves in Yellowstone National Park helped to control the deer population by preying on them. This led to a decrease in deer overpopulation and helped to restore balance in the ecosystem.

2. Wolves also influenced the behavior of deer by causing them to avoid certain areas where they were more vulnerable to predation. This altered grazing patterns and vegetation growth in those areas, which in turn affected the availability of food and shelter for other species in the ecosystem.
