Which of the following characterizes the biomass in an ecosystem?
Correct answer: A. No general statement can be made about relative biomass of different ecological groups
- A. No general statement can be made about relative biomass of different ecological groups
- B. The biomass of producers is less than the combined biomass of consumers and decomposers
- C. The biomass of secondary consumers is usually greater than the biomass of primary consumers
- D. The biomass of producers is generally greater than the biomass of primary consumers
Explanation
No single biomass relationship applies to every ecosystem: terrestrial systems often have more producer biomass, whereas aquatic systems can have an inverted biomass pyramid. Thus relative biomass depends on the ecosystem and its turnover rates.
