Q. How do biodiversity, the total number of living beings and the biomass respectively vary during the ecological succession?

The Biodiversity, the biomass of an ecosystem and the number of living beings tend to increase as the succession progresses and they stabilize when the climax stage is reached.

At the initial stage of the succession the use of the carbon dioxide and the fixation of carbon into the biomass are high, since the total number of living beings in the ecosystem is increasing. At the climax stage the use of the carbon dioxide by the photosynthesis equals the production by cellular respiration and the fixation of carbon into the biomass tends to zero.
