So how does a population stay under control?
A limiting factor is a factor that will keep a population from increasing out of control. These can include: predators, disease, parasites, and competition for resources.
Other factors that can affect a population are natural disasters and human impact.
Examples of Limiting Factors
Interaction of predator and prey
Higher the population the more likely a disease will spread.
As the population increases parasites can be spread more easily.
As population increases the amount of resources available cannot always provide what is needed.
Fires, volcanoes, earthquakes, and hurricanes are all examples of natural disasters that can affect animal populations.
Examples can be deforestation, urban sprawl etc.
