Ecological Efficiency
Calculate energy transfer efficiency between trophic levels.
Efficiency = (Energy at higher trophic level / Energy at lower level) × 100
Formula Explanation
Usually only about 10% energy is transferred to the next level.
Variables Explained
Energy units must be the same.
Solved Example
Herbivores get 1000 J from 10000 J of producers. Efficiency?
10%.
