Answer

The deer population will be too large to be supported by producers.

Download to view full explanation

When humans interfere with the natural balance within deer populations, they eliminate predators of the deer, which can lead to an overpopulation of deer. This overpopulation can cause the producers (plants) to become overgrazed, leading to a decrease in the amount of food available to the deer. As a result, the deer population will be too large to be supported by the producers.
