Answer: C. The population size became limited due to factors such as availability of food.
Explanation:
Out of all the choices, C is the most likely to happen since more often then not, food runs out because a species has too many members. C is an example of the environment’s carrying capacity limiting the chipmunk species.
Since we are not told if the chipmunk population is really small, interbreeding may not happen. Predators hunt prey, not eat fruits like chipmunks do (I’m assuming what chipmunks eat.) If there was a predator species that came in, they would hunt the chipmunks instead of competing for the same resources. D just doesn’t make much sense in my opinion because that wouldn’t limit the chipmunk population.
3: B Nervous system. 4: A Sensing and responding to its external environment.
B. Pine trees, this is the answer that was right after I took the test XD
