Question

B. If the biomass of the producers decreased, the organisms in the other trophic levels would

decrease because they depend on the biomass of the producers.
increase because they do not need the biomass of the producers.
stay the same because they have their own biomass.
go somewhere else because there is another biomass.

Answer 1

The correct option is A) decrease because they depend on the biomass of the producers.

Step-by-step explanation:

All the organisms in different trophic levels will possess most of their biomass. The first level of the trophic level has the most biomass. Usually, the first trophic levels will be the producers. The biomass reduces by an amount of 10% when moved from one trophic level to another one.

hence, if the biomass of the producers decreases the amount of biomass would also reduce enormously for other trophic levels.
