Explanation:
The climax communities are the communities that have reached the optimal number of species, as well as the optimal number of individuals of the species in the environment in accordance to the available food sources and space. These communities are in a state of equilibrium. Basically, the ecosystem has just the right amount of species, and just the right number of individuals of the species that it can support.
