Question

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

Options

• relative amount of biomass produced by producers

• number of species present

• intricacy of trophic relationships

• degree of specialization of species present

Answer 1

All of the following increase as community succession progresses, except for relative amount of biomass produced by producers.

Explanation:

As community succession progresses, species diversity, the intricacy of trophic relationships, and the degree of specialization increase as more complex and stable ecosystems develop. However, the relative amount of biomass produced by producers does not consistently increase; it may stabilize or even decrease in later stages as the ecosystem reaches a climax state in which biomass production and community respiration balance.
