Question

In the given food chain, suppose the amount of energy at fourth trophic level is 5 KJ, what will be the energy available at the producer level?
Grass $\to$ grasshopper $\to$ frog $\to$ snake $\to$ hawk

• A. 5 KJ
• B. 50 KJ
• C. 500 KJ
• D. 5000 KJ

Answer 1

The correct option is D 5000 KJ

In the given food chain if the amount of energy at fourth trophic level is 5 KJ, then 5000 KJ will be the energy available at the producer level. As only 10% of energy is trasferred to next higher trophic level, above producers, 500 KJ energy will be stored in body of grasshopper and 50 KJ in frog. 5 KJ energy will be present in the body of snake and 0.5 KJ in hawk.
