Detailed explanation-1: -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-2: -A second density-dependent limiting factor is predation. Predators kill and eat their prey, of course, so predation increases prey death rate and can cause negative growth rates – population decline.

Detailed explanation-3: -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-4: -The correct answer is (D) Severe weather patterns. Density-independent population growth factors are not affected by the population density.
