Final answer:
A stable population demonstrates little significant change in its size over time. It occurs when the birth rate and death rate of the population are roughly equal, resulting in a steady population size.

It means that the birth rate and death rate of the population are roughly equal, resulting in a steady population size. A stable population can occur when the population reaches its carrying capacity, which refers to the maximum number of individuals that an environment can sustainably support.
