The given diagram shows four food chains.
Correct answer: A. I
- A. I
- B. II
- C. III
- D. IV
Explanation
The energy transfer between trophic levels in a food chain is inefficient, with only about 10% of energy being transferred to the next level, and the rest lost as heat or used for metabolic processes. So the food chain with maximum levels will have least energy transferred to human.In this case I. So option A is correct. And option B,C and D are incorrect.
