Explanation:
Detailed explanation-1: -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.
Detailed explanation-2: -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-3: -Competition and predation are two important examples of density-dependent factors.
Detailed explanation-4: -Biotic factors are things like predation, parasitism, lack of food, competition with other organisms and disease.
