Question

1.	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 → Grasshopper → Frog → Snake → Hawk

(a)	5 k J
(b)	50 k J
(c)	500 k J
(d)	5000 k J

Accepted Answer

Soln:
Answer is (d) 5000 k J
Explanation:
Available energy level at a particular trophic level is 10 times the energy level at next tropic level. Hence, energy at third level trophic level is 50kj. Second level trophic has 500 KJ energy and 1st level trophic level (Producer) has energy of 5000 KJ.
