Detailed explanation-1: -Density-dependent Regulation Most density-dependent factors are biological in nature (biotic), and include predation, inter-and intraspecific competition, accumulation of waste, and diseases such as those caused by parasites. Usually, the denser a population is, the greater its mortality rate.

Detailed explanation-2: -As population size approaches the carrying capacity of the environment, the intensity of density-dependent factors increases. For example, competition for resources, predation, and rates of infection increase with population density and can eventually limit population size.

Detailed explanation-3: -Carrying capacity can be defined as a species’ average population size in a particular habitat. The species population size is limited by environmental factors like adequate food, shelter, water, and mates. If these needs are not met, the population will decrease until the resource rebounds.

Detailed explanation-4: -As a population approaches its carrying capacity, the growth rate slows because of limiting resources. Logistic Growth is density-dependent which means that the growth rate depends on the population density.
