Question

Of the total amount of energy that passes from one trophic level to another in a food chain, about $10\%$ is ___.

• A. reradiated as heat
• B. burnt in respiration
• C. stored in the body tissue
• D. transpired

Answer 1

The correct option is C stored in the body tissue

According to the $10\%$ rule, only $10\%$ of energy is transferred from one level to the next level of food chain, and in the remaining $90\%$ some part is used up metabolically for survival and the rest is lost as body heat. This $10\%$ that is transferred to the next trophic level is basically what is stored in the body tissue as food, and utilized as food by organisms in the higher trophic level.
