and the biomass respectively
vary during the ecological
succession?
Biodiversity, the number of living beingsand the biomass of an ecosystem tend
to increase as thand they stabilize we succession phen the climaxrogresses
stage is reached.
At the initial stage of the succession the
use of carbocarbon into the n dioxide and the fixation obiomass are high, since f
the total number of living beings in the

photosynthesis equals the production by
cellular carbon into the respiration biomass teand the fixation onds to zero.f
