Quizplus · Accepted Answer

All of these factors can contribute to regulating populations. Resource partitioning may limit the amount of resources available to a particular species, which can in turn limit their population size. Predation can directly reduce population numbers, as can social parasitism. Competition can result in decreased reproductive success or survival for individuals in a population, which can also limit overall population size.
