Question

All of the following increase as community succession progresses, except for

• A. Relative amount of biomass produced by producers
• B. Number of species present
• C. Intricacy of trophic relationships
• D. Degree of specialization of species present

Answer 1

The correct option is A Relative amount of biomass produced by producers

During the course of evolution, the simple and less adaptable life forms change into complex forms. The number of organisms inhabiting the area increases substantially and hence a food web is created with intricacy of trophic relationships. The organisms become more specialized leading to their defined niches. There isn't a compulsory increase in amount of biomass produced by producers.

So, the correct option is 'Relative amount of biomass produced by producers'.
