Which of the following statements about energy transfer efficiency in a food chain is correct?
hard Q9 of 15
Step-by-Step Solution
Step 1: Understand energy transfer efficiency
In ecosystems, only about 10% of energy is transferred from one trophic level to the next; the rest is lost as heat or used in metabolism.Step 2: Analyze options
Option stating 10% transfer is correct; 90% transfer is incorrect. Efficiency varies and is not equal at all levels.Step 3: Explain why others are wrong
Energy transfer is not highest between tertiary consumers and decomposers; decomposers recycle nutrients but do not receive energy in the same way.Final Answer:
Only about 10% of energy is transferred from one trophic level to the next → Option BQuick Check:
Energy transfer efficiency = About 10% per trophic level ✅
Quick Trick: Remember 10% energy transfer rule.
Common Mistakes:
- Assuming 90% energy transfer or equal efficiency.
