Fluctuations in the numbers of individuals in a population from year to year are called answer correct iteroparity density dependent equilibrium density density independent population dynamics

Flactuations in the number of individuals in a population from year to year are called population dynamics. It involves the study of sizes and ages composition of populations as a dynamical systems, and the biological and environmental processes driving them  which includes, birth rates, death rates, and immigration and emigration. 

Population dynamics is the answer

Yes yes yes very good
