Question

How do density-dependent factors affect population growth?

Answer 1

Density dependent factors are biotic factors.

Biotic factors include developmental times, mortality of the biocontrol agents according to age, and the mortality of the target population. Also, biotic regulatory factors include the interactions between members of the same species (intraspecific competition) as well as interactions with different species (interspecific competition). Interspecific competition can include the regulatory effects of herbivores or predators; interactions with other animal or plant species that utilize the same or similar resources such as food, shelter, light; or the effects of parasites and other disease-causing organisms
