How are density dependent limiting factors different from density independent limiting factors?

Density-dependent limiting factors cause a population's per capita growth rate to change—typically, to drop—with increasing population density. Density-independent factors affect per capita growth rate independent of population density. Examples include natural disasters like forest fires.

In this way, what is the difference between density dependent limiting factors and density independent limiting factors?

Explain the difference between a density-dependent limiting factor and a density-independent factor. Density-independent limiting factors affect populations no matter what their size is; density-dependent ones affect the population only when the number of organisms reach a certain level.

Beside above, is emigration a density independent limiting factor? Density-dependent limiting factors lower birth rates or increase death/emigration rates via increased intraspecific competition at higher population densities. Cycles of growth and decline limit some predator and prey populations.

Also Know, what are density independent limiting factors?

density-independent factor Any factor limiting the size of a population whose effect is not dependent on the number of individuals in the population. An example of such a factor is an earthquake, which will kill all members of the population regardless of whether the population is small or large.

How do parasites serve as a density dependent limiting factor?

Parasitism is considered as a density-dependent limiting factor. Given this case, parasites serve as a limiting factor to population growth because they cause a decrease in the population of the host species.
