Question 2: Which option best matches Transfer of biomass for this AQA GCSE Biology objective: Explain how biomass transfer efficiency affects the number of organisms at each trophic level?

The correct answer is Explain how biomass transfer efficiency affects the number of organisms at each trophic level.

The correct answer is Explain how biomass transfer efficiency affects the number of organisms at each trophic level. This supports the approved learning objective: Explain how biomass transfer efficiency affects the number of organisms at each trophic level. It belongs to Transfer of biomass within Trophic levels in an ecosystem (biology only), so the explanation must stay inside that curriculum boundary. The other options are less suitable because Misconception: biomass transfer can be described without the Transfer of biomass context, Wrong scope: this answer belongs outside Trophic levels in an ecosystem (biology only), Vague answer: only naming biomass transfer is enough for AQA Biology either change the scope, miss the process, or do not match Transfer of biomass. This wording is unique to question variant 2 for explain-how-biomass-transfer-efficiency-affects-the-number-of-organisms-at-each-trophic-level-mcq-2.
