Answer:
A. It disrupts the balance between predators and prey
Explanation:
The effect on the ecosystem when populations of white - tailed deer are overhunted is that it disrupts the balance between predators and prey within the ecosystem.
The whited - tailed deer is the usually the prey. The carnivores are the cats and other flesh eating animals. When the deer is over-hunted, there are more predators compared to prey. This leads to a serious imbalance and a high level of competition for the scarce prey.
