Question

At carrying capacity, the population growth rate is ______.

Answer 1

At carrying capacity, the population growth rate is zero.

Explanation:

This happens because the environment can support only a maximum number of individuals, and the birth rate equals the death rate. Hence, population size stabilizes without further growth. This is explained by the logistic growth model, where population growth slows down as it approaches the carrying capacity due to limited resources and increased competition, resulting in zero net increase in population size.
