Why Is Disease a Density Dependent Limiting Factor

Parasitism and disease are density-dependent effects, because the denser the host population, the more easily parasites can spread from one host to another.

Why is disease a density-dependent factor?

Disease is one of the most notable examples of density dependence. Diseases spread quickly through dense populations because individuals live in closer proximity to each other. Parasitism is similar to disease in that it also spreads faster through dense populations.

Why is disease a limiting factor?

If a population becomes diseased, the population may decrease and the population of animals that eat the diseased animals will also decrease. In nature, populations usually balance themselves. Sometimes when man impacts populations, they can’t always reestablish a natural balance.
