BRAINCAKECalculating Percentage Efficiency
The efficiency of energy transfer between two trophic levels is calculated as:
percentage efficiency = (energy transferred to the higher level / energy available at the lower level) × 100
The value on the bottom is always the energy at the level the energy came from. Both values must be in the same units.
