The diagram illustrates how energy passes along a food chain. Sunlight supplies $1 \times 10^{6}\ \text{kJ m}^{-2}\ \text{y}^{-1}$ to green plants. The green plants have $27\,000\ \text{kJ m}^{-2}\ \text{y}^{-1}$, and $3000\ \text{kJ m}^{-2}\ \text{y}^{-1}$ is dissipated as energy. What percentage of the energy is used by the green plants for photosynthesis?
- A$0.03\%$
- B$0.30\%$
- C$2.70\%$
- D$3.00\%$
