These wolves are known to not immigrate or migrate. If local biologists note that the population size is constant, what could be said about the birth rate and death rate of these wolves?

The correct answer would be - the death rate and birth rate are equal.

Explanation:

Population growth or population size depends on the number of individuals increase or decrease in a population in a certain period of time. An increase in number could be by any means such as immigration or birth of new individuals whereas a decrease could be possible by migration or death.

In this case, emigration or immigration are not present and the size of the population is constant which means the size completely depends on the death and births of individuals in the population.

If the population size is constant it means the number of increase and decrease of individuals is equal, so the death rate and birth rate would be equal.
