Antarctic marine food chain pyramid of biomass

Calculate the percentage of the biomass of the krill that is transferred to the leopard seals.

Use the equation:

percentage=biomass of leopard sealsbiomass of krill×100 \text{percentage} = \frac{\text{biomass of leopard seals}}{\text{biomass of krill}} \times 100 percentage=biomass of krillbiomass of leopard seals​×100
