If 20 J of energy is trapped at the producer level, then how much energy will be available to eagle as food in the following food chain?
Plant → Rabbit→ Snake → Eagle
Answer & explanation
Correct answer: option 1
According to 10% law of energy flow, eagle will receive 0.02 J of energy as top consumer.
Energy received by the organisms at different trophic level can be seen as follows
Plant → 20J
Rabbit → 20 ×10% =2 J
Snake → 2 ×10% =0.2 J
Eagle → 0.2 ×10% =0.02 J
