Which factor would most likely limit the size of a population?

B) A decrease in the population growth rate as density increases
C) A decrease in mortality as density increases
D) Multiplicative growth
E) Additive growth

Question

Quizplus · Accepted Answer

As population density increases, resources become more limited and competition for those resources increases. This can lead to a decrease in the population growth rate, ultimately limiting the population size. Choice A is incorrect because an increase in population growth rate would lead to population growth, rather than limiting population size. Choice C is incorrect because a decrease in mortality would actually increase population size, rather than limit it. Choices D and E refer to specific types of population growth models and are not directly related to population size limitations.
