Question 4: Which option best matches Transfer of biomass for this AQA GCSE Biology objective: Recall that only about one tenth of biomass is transferred to the next trophic level?

The correct answer is comparison focus: Recall that only about one tenth of biomass is transferred to the next trophic level..

The correct answer is comparison focus: Recall that only about one tenth of biomass is transferred to the next trophic level.. This supports the approved learning objective: Recall that only about one tenth of biomass is transferred to the next 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: trophic level 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 trophic level 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 4 for recall-that-only-about-one-tenth-of-biomass-is-transferred-to-the-next-trophic-level-mcq-4.
