The oldest stage of succession, is the stage where there is stability, and balance in the biomass, such that the number of species is relatively constant, or the plateau region of the biomass time graph. Community changes alter the ecosystem in ways that favor competitors, and species replace one another in a somewhat predictable manner until a stable community is reached.
