Document Summary

Resources are limited the logistic model of population growth addresses this limitation. The rate of population growth does not remain constant with this model- it declines with population growth. So: when there are few individuals relative to the amount of resources-the population grows exponentially. But: as the population grows density-dependent limiting factors such as competition begin to slow growth. This is because there is now competition for food, shelter, nesting sites and other essential resources. 1: parasitism and disease also increase with population density and also slow growth. As a result of density-dependent limiting factors population growth begins to slow. Population growth continues until it eventually levels off at the environment"s carrying capacity: The maximum possible population growth under optimal conditions.
