Answer:
c . The predator population was overpopulated in the forest
Explanation:
As per the condition mentioned in the observation, it can be concluded that the predator population was overpopulated in the forest.
Predators are the organisms that kill and eat another organism, its prey. In the given observation deer and squirrel are the predators that are overpopulated in the forest.
Because of the overpopulation of deer, most of the trees have missing bark, limbs, and leaves and due to the overpopulation of squirrel, birds are unable to nesting as they attack the eggs of birds.
Hence, the correct option is "c".
