When wolves disappeared from Yellowstone National Park, the deer population increased. This led to overgrazing of vegetation, which affected various plant species, including willow trees. Consequently, the ecological balance was disrupted, impacting other species in the park, such as bears that relied on certain plant species for food. So, the correct response is:

The deer population increased.
