Basic Population Concepts
... • Absence of natural enemies allows an herbivore population to exceed carrying capacity which results in overgrazing of the habitat. • The herbivore population subsequently crashes. • The size of the herbivore population is maintained so that overgrazing or other overuse does not occur. ...
