Question

the carrying capacity of any population will stay the same
a as long as predators do not increase.
b unless environmental conditions change.
c regardless of emigration and immigration.
d even though the birth rate exceeds the death rate.

Explanation:

Carrying capacity is the maximum population size of a species that an environment can sustain indefinitely. It is determined by environmental factors such as food availability, water supply, and habitat space. Changes in these environmental conditions will alter the carrying - capacity. Predator numbers, emigration/immigration, and birth/death rates do not directly change the carrying - capacity of the environment for a population on their own, but environmental changes do.

Answer:

B. unless environmental conditions change.
