Expert

Verified

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

At the preliminary stage of succession the employ of carbon dioxide and fixation of carbon in the biomass are elevated, since total number of living beings in ecosystem is rising. At the climax stage the employ of carbon dioxide by photosynthesis equals production by cellular respiration and the fixation of carbon in the biomass tends to nil.
