Question

Ascending trophic level in grazing food chain pyramid represents

• A. Gradual decrease in biomass from apex to base
• B. Gradual decrease in biomass from producers to the tertiary consumers
• C. Gradual increase of the biomass from producers to the tertiary consumers
• D. No change in biomass

Answer 1

Answer: (B)

Gradual decrease in biomass from producers to the tertiary consumers

Pyramid of biomass represents the total mass of organisms at each trophic level. The pyramid of biomass is upright in grazing food chain. In upright pyramid of biomass, the trophic levels are in ascending orders. The biomass at the base (producers) is maximum and biomass at the apex is minimum (tertiary consumers). The ascending trophic level in grazing food chain pyramid represents gradual decrease in biomass from producers to the tertiary consumers.

Thus, the correct answer is 'Gradual decrease in biomass from producers to the tertiary consumers.'
