Definition
Density dependent factors are environmental factors whose effects on populations depend on their density. These factors include competition for resources, predation, and disease transmission.
Intraspecific Competition: Intraspecific competition refers to the competition between individuals of the same species for limited resources.
Predator-Prey Interactions: Predator-prey interactions involve the relationship between predators (animals that hunt and kill other animals) and their prey (animals that are hunted and killed by predators).
Disease Dynamics: Disease dynamics refer to how diseases spread within populations, including factors such as transmission rates and host resistance.
