In case of plant succession, when climax is reached, the net productivity of the ecosystem

Options

  1. AContinues to decrease
  2. BBecomes halved
  3. CBecomes stable
  4. DBecomes zero

Correct answer

C. Becomes stable

Step-by-step solution

In the early stages of plant succession, photosynthesis is more than respiration (P > R). In the climax stage, huge respiration of living biomass occurs and photosynthesis is equal to respiration (P / R = 1 or P = R). Hence, net productivity becomes stable, when the climax stage is reached in plant succession.
