Quizplus · Accepted Answer

According to the logistic growth equation, population growth is zero when N reaches the carrying capacity K. Therefore, option C is the correct choice. Option A is incorrect because the number of individuals added per unit time decreases as N approaches K. Option B is also incorrect because the per capita growth rate (r) actually decreases as N approaches K. Option D is incorrect because the population growth rate decreases as K decreases, making it more difficult for the population to grow exponentially. Option E is incorrect because the birth rate is highest when the population size is near the carrying capacity, not approaching zero.
