The correct answer is exam focus: Explain how biomass is lost because not all ingested material is absorbed.. This supports the approved learning objective: Explain how biomass is lost because not all ingested material is absorbed. 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: absorbed 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 absorbed 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 5 for explain-how-biomass-is-lost-because-not-all-ingested-material-is-absorbed-mcq-5.
