Question

what best describes a population with a growth rate equal to zero?
decreasing
inverting
growing
stable

Explanation:

When the growth rate of a population is zero, it means that the number of births is approximately equal to the number of deaths (in the case of human - like populations, also considering immigration and emigration if applicable). A stable population has no net change in size over time, which is consistent with a growth rate of zero. A decreasing population would have a negative growth rate, a growing population would have a positive growth rate, and "inverting" is not a standard term to describe population growth rate characteristics in this context.

Answer:

D. stable
