Solution
The correct option is A 10 J
According to Lindemann's 10% law of energy transfer, only 10% of the energy available at any trophic level is transferred to the next trophic level.
In the given question 1000 J of energy is present at the producer, so 10% of this energy is available to primary consumers (herbivores) and 10% of herbivores energy available to primary carnivores (secondary consumers).
Energy to primary consumers = 1000×10÷100 = 100 J
Energy to primary carnivores = 100×10÷100 = 10J
Thus 10 J energy will be available to the primary carnivores as food in the food chain.
