Population and Carrying Capacity
... 'Carrying capacity' refers to the size of a population that can be supported indefinitely by the resources and services of a given ecosystem. Beyond this carrying capacity, no additional individuals can be supported, at least not for long. When a population is maintained at its carrying capacity, ...
