Table 1 shows the biomass of organisms at each stage in a grassland food chain.
| Organism | Biomass in arbitrary units |
|---|---|
| Grass | 1200 |
| Grasshoppers | 150 |
| Frogs | 30 |
| Hawks | 6 |
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
