Why A forest ecosystem can support a limited number of bears?

A forest ecosystem can support a limited number of bears due to factors such as available food resources, territory size, and habitat quality. Each bear requires a substantial amount of food, primarily from plants and smaller animals, which can be limited in a given area. Additionally, bears need sufficient space to establish territories and avoid competition with other bears. If the population exceeds the carrying capacity of the ecosystem, it could lead to resource depletion and increased mortality rates.
