Answer: Carrying capacity is the number or quantity of people or things that can be conveyed or held by a vehicle or container, or the number of people, other living organisms, or crops that a region can support without environmental degradation.
Food availability in any habitat is paramount to survival of a species. Predators, carnivores, must have prey availability.
Animals must have water to help with food digestion, to help control and regulate body temperature, and to help eliminate waste products from the body.
Conditions within or adjacent to an environment also affect its carrying capacity. For example, if the environment is located close to a human population, this may affect its carrying capacity.
Animals need a place to shelter from poor conditions, and to provide a place for reproduction. Sufficient space within a habitat allows the animals that inhabit it better opportunities to find adequate food and water.
