Ecological succession

Question

Explain how do biodiversity, biomass, and total number of living beings respectively change during the ecological succession?

Answer 1

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

At initial stage of succession, use of carbon dioxide and fixation of carbon into the biomass are high, as the total number of living beings within the ecosystem is increasing. At climax stage, use of the carbon dioxide by photosynthesis equals the generation by the cellular respiration and fixation of the carbon into the biomass becomes zero.
