Populations approach a stable equilibrium when

Question

Quizplus · Accepted Answer

A population approaches a stable equilibrium when its growth rate nears zero, meaning that the birth rate equals the death rate and there is no net migration. Option A is incorrect because a depleted resource would not support population growth, and there would be no equilibrium to approach. Option B is incorrect because although resources may be plentiful, the population growth rate still needs to slow down for the population to approach equilibrium. Option D is incorrect because populations exceeding carrying capacity would experience a decline in resources and an increase in competition, which would lead to a reduction in population size rather than an equilibrium.
