Detailed explanation-1: -A density-dependent factor is a factor whose effects on the size or growth of a population vary with the population density. Density-dependent factors typically involve biotic factors, such as the availability of food, parasitism, predation, disease, and migration.
Detailed explanation-2: -Density-dependent limiting factors tend to be biotic-having to do with living organisms. Competition and predation are two important examples of density-dependent factors.
Detailed explanation-3: -Any factor in the environment that does not depend on the number of members in a population per unit area is a density-independent factor (such as weather, fire, pollution) Define density – dependent factor.
Detailed explanation-4: -Predation. Predation is another density-dependent factor. If a species of prey grows in population, predators are going to take advantage of the increased abundance of a food source and will tend to consume more of that prey the larger its population grows.
