Instructions
If we want the percentage efficiency of energy transfer between producers and primary consumers.
1. Calculate the total energy that came into the level of the food chain: 4,500kJ + 500kJ = 5,000kJ
2. Identify how much energy is transferred to the next level: 500kJ
3. Calculate the efficiency of this transfer using the equation:
(Energy transferred to next level ÷ Total energy in) X 100
(500kJ ÷ 5,000kJ) X 100 = 10%
This shows the percentage efficiency of energy transfer between producers and primary consumers in this ecosystem is 10 per cent.
