How do biodiversity, the total number of living organisms and biomass vary during ecological succession?

Homework Answers

Answer #1

Variation of biodiversity during the ecological succession:

  • Biodiversity is the number of living organisms and the biomass of an ecosystem tend to increase as the succession progresses and stabilize when the climax stage is reached.
  • During the initial stage of succession,the use of carbon dioxide and the fixation of carbon into the biomass are high because the number of organism in the ecosystem is increasing.
  • During the climax stage,the use of carbondioxide by photosynthesis equals the amount of carbon dioxide produced by the cellular respiration.

Carbon Dating: All living organisms contain two isotopes (types) of carbon; carbon-12 ( 12C) and carbon-14 (14C). Carbon-12 is stable, meaning that its atoms do not decay. Carbon-14 however, is radioactive or unstable, meaning that an atom of carbon-14 may decay. It does this by throwing off an electron and thus transforming itself into Nitrogen 14. The ratio of carbon-14 to carbon-12 is the same for all living organisims, about 1/10, 000. However, once an organisim dies the carbon-14 begins...
