density-dependent factor
-
Disease: Outbreaks of disease tend to occur when a population has increased and population density is high.
-
Parasites: When population density is high, parasites spread in a way similar to the way disease spreads.
Predators: The figure below illustrates how the interaction of predators and prey limits the populations of both groups.
