Question

Quizplus · Accepted Answer

Parasites can limit population growth and keep populations below carrying capacity, similar to how predators can. Parasites consume resources from their hosts, which can limit the growth and reproduction of the host population. Interspecific competitors can also limit population growth, but they do not necessarily keep populations below carrying capacity or limit competitive exclusion in the same way as predators and parasites. Facultative and obligate mutualists and commensals do not have direct negative effects on population size.
