The idea originally comes from farming: the carrying capacity is the maximum number of people that can be fed on the food produced in an area. Achetez neuf ou d'occasion pptx, 703 KB.

An ecosystem's carrying capacity for a particular species may be influenced by many factors, such as the ability to regenerate the food, water, atmosphere, or other necessities that populations need to survive. Carrying capacity is the maximum population size that a species can maintain indefinitely in a given area–that is, without diminishing the capacity of the area to sustain the same population size in the future. It is assumed that the birth and death rates are density-dependent, the former declining and the latter increasing as the population size (N) increases and food per individual decreases.
