Which term describes a population that remains unchanged for long periods, with births and deaths balancing each other?

Explanation:
Balancing births and deaths keeps population size constant over time. When resources limit growth and the population approaches carrying capacity, the increase slows and the size levels off, creating a plateau. The flat portion means the net growth rate is about zero because births balance deaths. Immigration could alter this balance, but with births balancing deaths, plateau best describes the situation.
