In an ecosystem, the producers have a total of $3 \times 10^6\ \text{kJ m}^{-2}\ \text{yr}^{-1}$ available to them. In theory, what amount of this energy would be passed on to tertiary consumers?
- A$3 \times 10^4\ \text{kJ m}^{-2}\ \text{yr}^{-1}$
- B$3 \times 10^3\ \text{kJ m}^{-2}\ \text{yr}^{-1}$
- C$3 \times 10^2\ \text{kJ m}^{-2}\ \text{yr}^{-1}$
- D$3 \times 10^1\ \text{kJ m}^{-2}\ \text{yr}^{-1}$
