Detailed explanation-2: -The predator–prey relationship is an example of a density-dependent limiting factor. A density-dependent limiting factor affects the population density (number of organisms per a given area) when it reaches a certain level. Other examples of density-dependent limiting factors are competition, parasitism, and disease.

Detailed explanation-3: -Predator-Prey Relationships The effects of predators on prey and of prey on predators are both very important density dependent population controls. Each populations change in size is driven by the size of the other population.

Detailed explanation-4: -Density-dependent factors include disease, competition, and predation.
