In ecology, a density-dependent factor, also known as a regulatory factor, is any force that modifies the size of a population of living creatures in response to population density.
Because of their propensity to maintain population densities, density-dependent factors are also known as regulating factors.
Population size and a density-dependent factor's level of control are correlated, therefore an increase in population will increase the influence of the limitation. Density-dependent factors involve biotic factors such as availability of food , predation, competition, parasitism and disease.
