Question

due to construction of a new housing development, a population of chipmunks have migrated into a new area already occupied by a population of squirrels. the result of the human impact is-- the population count of squirrels and chipmunks will stay the same. the population count of squirrels and chipmunks will increase due to cooperation. the population count of squirrels and chipmunks will decrease due to competition. the population of squirrels will leave the area.

Explanation:

Chipmunks have migrated into an area with squirrels. In nature, when two species compete for the same resources (habitat, food etc.), it often leads to a decrease in one or both populations. Here, the chipmunks' arrival will likely cause competition with the squirrels, resulting in a decrease in the squirrel - chipmunk population due to competition.

Answer:

The population count of squirrels and chipmunks will decrease due to competition.
