The term for the maximum number of individuals that an ecosystem can support is called the carrying capacity. Carrying capacity refers to the maximum population size of a given species that an environment can sustain indefinitely, given the food, water, and other resources available. It is influenced by various factors such as resource availability, environmental conditions, competition, predation, and disease.

The concept of carrying capacity is important in ecology as it helps in understanding the dynamics of population growth and the ability of an ecosystem to support its inhabitants. When populations exceed their carrying capacity, it can lead to overpopulation, resource depletion, environmental degradation, and potential population declines.
