Question

Which of the statement is correct regarding food chain?

• A. Passage of food from one trophic level to the next higher one
• B. Passage of energy from one trophic level to the next higher one
• C. Dissipation of energy at successive trophic levels
• D. All of the above

Answer 1

The correct option is D All of the above

Food chain in an ecosystem is defined as the passage of food from one trophic level to the next higher trophic level. The transfer of food from one trophic level to the next level results in the passage of energy through these trophic levels. It starts with the producers and ends with the top consumers. It results in the dissipation of energy at successive trophic levels. About 10% of total energy is transferred to the successive trophic level in a food chain.

Thus, the correct answer is 'All of the above.'
