Density-dependent factors ______________

Question

Quizplus · Accepted Answer

Density-dependent factors are biotic factors that have an increasing effect as population density increases. This includes the effects of disease, predators, and food availability on a single species within a community, as competition for resources and proximity to one another can increase as population density increases. A hard freeze or rainfall could have an effect on a community, but would not necessarily be density-dependent factors as they do not specifically vary based on population density. Density-dependent factors may also lead to decreased population size or even extinction of certain species, but do not necessarily lead to a decrease in the number of species in an ecosystem.
