What does "carrying capacity" refer to in an ecosystem?

Carrying capacity refers specifically to the maximum population size that an environment can sustain over time without degrading the habitat. This concept takes into account various limiting factors, including food availability, habitat space, water supply, and other essential resources needed for survival. When a population exceeds its carrying capacity, the environment may suffer due to overuse of resources, leading to habitat destruction and a decline in population size.

While the number of species in a habitat, food availability for species, and the biodiversity index are all important ecological concepts, they do not directly define carrying capacity. Instead, carrying capacity focuses on the balance within an ecosystem regarding the sustainable population of a particular species or group of species. This understanding is crucial for wildlife management and conservation efforts, as it helps determine how to maintain healthy ecosystems while allowing for species population growth.
