The correct answer is-

A) predators, like snakes.

As per the information given in the question, there is plentiful wildlife in the  pineywoods. It is inhabited by more than 100 species of birds and many small mammals such as cottontail rabbits and squirrels.

In order to keep balanced population in pineywoods habitat, it is required to include predators like snakes ( that capture and eat other organisms as source of energy such as birds, rats, and other small mammals) as they will prevent the organism from overcrowding in the habitat.

Thus, it will maintain a balanced population in the pineywoods.

Therefore, option A) is the right answer.

its temperature is increasing. this causes molecular vibrations to increase.
