What is carrying capacity?  The maximum size that a population can reach in an ecosystem.  The moose population’s peak appears to be around 1,500.  The population of moose would still be limited because there is only so much food and space that is available.  An ecosystem’s carrying capacity is different for each population.

Limiting Factors  Biotic factors can be limiting factors because they include interactions between populations, competition, predation, and parasitism.  Abiotic factors are also limiting because of temperature, availability of water or minerals, and wind exposure.

Population Growth and Decline  Population size depends how often organisms reproduce.  This affects the stability of an ecosystem.  For example, bears reproduce every two years. If not enough food is available, the female bear’s reproductive cycle is delayed. Then, the bear population does not grow.

Example: This picture shows the carrying capacity of a car. When the Carrying Capacity of a Car is decreased, the weight it can carry is decreased. Like in an environment, when the population in an environment is decreased.
