Q. In plant succession, when climax is reached, the net productivity
A) Continues to increase
B) Becomes halved
C) Becomes stable
D) Becomes zero
Explanation
In early stages of plant succession, photosynthesis is more than respiration (P > R) and in climax stage, huge respiration of living biomass occurs and (P / R = 1) or, photosynthesis is equal to respiration (P = R). So, net productivity becomes stable, when climax stage is reached in plant succession.
