In 1906, there were an estimated 4,000 deer on the Kaibab Plateau. The government decided to create a preserve for them. Livestock had overgrazed the food on the plateau. The Forest Service chose to move the horses, sheep, and cows off of the preserve. They also decided to remove the deers' natural predators. In 1920, the Forest Service discovered that the number of deer in the preserve was very large. By 1923, most of the deer were starving from a lack of food. Which statement best describes what happened on the Kaibab Preserve?

• Overgrazing by livestock caused the deer on the Kaibab Plateau to starve.

• Because there were no natural predators, the deer population grew too large.

• The natural predators could not keep up with the growth of the deer population.

• The large growth and starvation of the deer population was simply a natural event.

• Increase the local fish population.

• Increase the dissolved oxygen available.

• Increase the amount of habitat available.
