To protect the wildlife at Yellowstone, park rangers killed every wolf they could find. Why did the park rangers notice a decrease in plant life soon after?

• Before the rangers killed all the wolves, the wolves guarded the plants.

• There were no natural predators to keep the herbivore population under control.

• The herbivores were starving because the rangers killed their food sources.

• There was an increase in other predators which consumed all other food sources.
