13. Ranchers lobbied the government to eradicate wolves from Yellowstone National Park. Five years later the deer population had increased fivefold. The following winter 70% of the deer starved to death. Explain why this was bound to happen.

The overgrowth in deer population led to a food shortage.

Explanation:

Since the eradication of the wolves, the deer had no predator to keep their total population in check. Due to the vast amount of deer the food in the area was being eaten at a faster rate. Most of the deer died do to their environment not being capable of feeding that many deer.
