Question
Energy transfer in a food chain is generally 90% efficient
Correct Answer
Option B is the correct answer.
Detailed Explanation
This statement is false. Energy transfer between trophic levels is generally very inefficient, typically around 10% efficient. This means only about 10% of the energy at one trophic level is passed on to the next; the rest is lost as heat through metabolism.
Hint
Is energy transfer efficiency around 10% or 90%?
