biomass

In Transfer of biomass, biomass means biomass is a curriculum-aligned term linked to the learning objective: Explain how biomass is lost because not all ingested material is absorbed. This matters in Trophic levels in an ecosystem (biology only) because it supports the learning objective to explain how biomass is lost because not all ingested material is absorbed. Use biomass only in this subtopic-relevant sense so the definition stays concise, curriculum-specific, and useful for AQA GCSE Biology revision. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.
