Answer 1

When wolves disappeared from Yellowstone National Park, one of the most significant ecological impacts was the increase in the deer population. Without wolves as predators, deer numbers rose, leading to overgrazing of vegetation, particularly willow and other plants. This chain reaction affected various aspects of the ecosystem, including the populations of other species like bears, which rely on berries and other vegetation that were diminished due to the excessive browsing by deer. Therefore, the correct response is:

- The deer population increased.
