In a stable population where births equal deaths, the population is in which state?

Explanation:
Zero net growth occurs when births equal deaths, so the population size remains constant over time. That constant, unchanging level is described as a plateau. Exponential growth would require births to exceed deaths and the numbers to rise; decline means deaths exceed births. Carrying capacity is the environmental limit that can constrain growth, and a population at carrying capacity often has near-zero growth, but the state of no change in size is best described as a plateau.
