OrganismBiomass in arbitrary units
Grass1200
Grasshoppers150
Frogs30
Hawks6

Calculate the percentage of the biomass of the grasshoppers that is transferred to the hawks.

Use the equation:

percentage=biomass of hawksbiomass of grasshoppers×100\text{percentage} = \frac{\text{biomass of hawks}}{\text{biomass of grasshoppers}} \times 100percentage=biomass of grasshoppersbiomass of hawks​×100
