What factors determine the carrying capacity of a population?

The carrying capacity of a population is determined by several factors, including the availability of resources such as food, water, and shelter, as well as environmental conditions like climate and habitat space. Additionally, biotic factors such as competition, predation, and disease can influence population dynamics. Human activities, such as land use changes and pollution, also play a significant role in shaping carrying capacity. Ultimately, it represents the maximum number of individuals that an environment can sustainably support over time.
