Question

In a pyramid of biomass, primary producers have a dry biomass of 809 kg/$m^2$. The biomass at tertiary consumer level would be

• A. 37 kg/$m^2$
• B. 11 kg/$m^2$
• C. 5 kg/$m^2$
• D. 1.5 kg/$m^2$

Answer 1

The correct option is D 1.5 kg/$m^2$

In an ecological pyramid, pyramid of biomass indicates the biomass at each trophic level. In a pyramid of biomass, there is a sharp decrease in biomass at higher trophic levels. In a pyramid of biomass, primary producers have a dry biomass of 809 kg/m${}^2$. The biomass at primary consumer level will be 37 kg/m${}^2$. The biomass at secondary consumer level will be 11 kg/m${}^2$. The biomass at tertiary consumer level will be 1.5 kg/m${}^2$.

Thus, the correct answer is '1.5 kg/m${}^2$.'
