Climax stage of the ecological succession

Question

Describe climax stage of an ecological succession. Discuss in detail.

Answer 1

The climax stage is defined as the stage of ecological succession where the community of an ecosystem becomes stable and does not undergo the important modification. Within the climax community practically all the ecological niches are explored and biodiversity is the greater possible. Within this stage biomass, the photosynthesis rate and the cellular respiration reach their maximum levels and therefore, the net primary production (NPP = organic material made by the producers - organic material consumed in the cellular respiration of the producers) tends to become zero. At climax, the amount of oxygen liberated by the photosynthesis becomes practically equal to oxygen consumed by respiration.
