A population’s carrying capacity

(A) may change as environmental conditions change.

(B) can be accurately calculated using the logistic growth model.

(C) increases as the per capita population growth rate decreases.

(D) can never be exceeded.

In ecology, the scientific study that statistically and systematically analyzes population like human beings and changes in population size is called demography.

The field of ecology describes the environment as the surrounding and external conditions like resources and stimuli affecting the living organism living in it.

Thus, the population’s carrying capacity changes based on the food and space availability in an environment.

Therefore, the given statement is true.

The logistic growth model represents the limited resources due to environmental resistance that restricts population growth.

Thus, the logistic growth model does not provide an accurate calculation of carrying capacity.

Therefore, the given statement is false.

When the individual numbers change within a population over a specified time, it is called the population growth rate.

Thus, the carrying capacity becomes steady when there is a decrease in the per-capita population growth rate.

Therefore, the given statement is false.

When species live in an area, then their average size is determined by the population carrying capacity.

Thus, the population carrying capacity will exceed due to the availability of too many resources.

Therefore, the given statement is false.
