Figure 1 shows the flow of energy through a managed marine aquaculture food chain consisting of microalgae and brine shrimp (Artemia). The numbers represent energy flows in kJ m−2 year−1\text{kJ}\ \text{m}^{-2}\ \text{year}^{-1}kJ m−2 year−1.
The brine shrimp is more efficient than the microalgae at converting energy.
The energy conversion efficiency of the brine shrimp is 9.00%9.00\%9.00%.
Calculate how many times more efficient the brine shrimp is at converting energy than the microalgae.
The equation for energy conversion efficiency is:
energy conversion efficiency=energy used for growthenergy input×100\text{energy conversion efficiency} = \frac{\text{energy used for growth}}{\text{energy input}} \times 100energy conversion efficiency=energy inputenergy used for growth×100
