Solution
The correct option is C 100 J
The 10% law of energy flow states that when energy is transferred from one trophic level to another, only 10% of it is transferred to the next trophic level. So, 90% of the energy is lost. The producers accumulated 10kJof energy of which only 1000J will be transferred to the grasshoppers. Of that only 100J will be transferred to the next trophic level.
