Answer:

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

  • Ecological succession refers to the recovery of the ecosystem after disturbance.
  • With the increase in ecological succession, both the biodiversity and biomass of an ecosystem tend to increase. Biodiversity refers to the range and variety of living organisms within a specified area whereas biomass refers to the total mass of living organisms in a specific area at a given time.
  • This occurs due to gradual and systematic change in an ecosystem that is caused due to replacement of one community with the other community till a stable climax is achieved and the community is dominated by well-adapted species. Ecosystems with high biodiversity are also more resistant to disturbance or damage.
  • As the ecological succession occurs, complex food webs evolve and total biomass of the ecosystem increases.
