Question

The biomass of each succeeding trophic level is

• A. More than the one preceding
• B. Less than the one preceding
• C. Constantly fixed
• D. Equal to next trophic level

Answer 1

Answer: (B)

Less than the one preceding

Biomass the total mass of individuals at each trophic level. The pyramid of biomass represents the total mass of individuals at each trophic level. The biomass of each succeeding trophic level is less than the one preceding trophic level. In other words, total biomass of organisms at each trophic level decreases from the bottom to top. About 10% of energy consumed is only converted into biomass.

Thus, the correct answer is 'Less than the one preceding.'
