Table 1 shows the biomass of organisms at each trophic level in a marine kelp forest food chain.

OrganismBiomass in kg\text{kg}kg
Giant Kelp15 000
Sea Urchins1 800
Sea Otters225
Great White Sharks27

Calculate the percentage of the biomass of the sea urchins that is transferred to the great white sharks.

Use the equation:

percentage=biomass of great white sharksbiomass of sea urchins×100\text{percentage} = \frac{\text{biomass of great white sharks}}{\text{biomass of sea urchins}} \times 100percentage=biomass of sea urchinsbiomass of great white sharks​×100
