What happened to Yellowstone National Park when wolves disappeared?
VashaNatasha [74]

Answer:

B. The deer population increased

Explanation:

Wolves would primarily hunt the deer, therefore if there were no wolves around then the deer were able to reproduce without the threat of wolves eating them.

Wolves wouldn't hunt bears because it is increasingly harder for them to kill bears than deer.

The wolves wouldn't really influence the environment because they are mainly carnivores.
