Which density-dependent factor controls the size of a population?

A) wind velocity
B) light intensity
C) nutrient supply
D) amount of precipitation
E) wave action in an intertidal zone

Nutrient supply is a density-dependent factor that can limit the growth and size of a population. As the population size increases, the demand for nutrients also increases, and if the supply of nutrients is limited, it can lead to decreased reproduction rates, lower survival rates, and higher susceptibility to diseases or predation, ultimately leading to a decrease in population size.
