A muskrat population is growing exponentially. What might cause this population to enter logistic growth?

Answer: One cause that might cause the population of this semi aquatic rodents to enter a logistic growth would be the elimination of predators from their environment and the increase of food. The reason being that they are rodents with an adaptable lifestyle and an omnivorous diet. With no predators they would quickly adapt to their environment and increase their birth rate.

I hope it helps, Regards.
