Trophic levels in an ecosystem (biology only) key terms

trophic level

trophic level is a curriculum-aligned term linked to the learning objective: Recall that only about one tenth of biomass is transferred to the next trophic level..

Recall

In Transfer of biomass, Recall means recall is a curriculum-aligned term linked to the learning objective: Recall that only about one tenth of biomass is transferred to the next trophic level. This matters in Trophic levels in an ecosystem (biology only) because it supports the learning objective to recall that only about one tenth of biomass is transferred to the next trophic level. Use Recall 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.

absorbed

absorbed is a curriculum-aligned term linked to the learning objective: Explain how biomass is lost because not all ingested material is absorbed..

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.

egestion

egestion is a curriculum-aligned term linked to the learning objective: Explain how biomass is lost in faeces through egestion..

faeces

In Transfer of biomass, faeces means faeces is a curriculum-aligned term linked to the learning objective: Explain how biomass is lost in faeces through egestion. This matters in Trophic levels in an ecosystem (biology only) because it supports the learning objective to explain how biomass is lost in faeces through egestion. Use faeces 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.

carbon dioxide

carbon dioxide is a curriculum-aligned term linked to the learning objective: Explain how absorbed material is lost as waste, including carbon dioxide and water from respiration..

respiration

In Transfer of biomass, respiration means respiration is a curriculum-aligned term linked to the learning objective: Explain how absorbed material is lost as waste, including carbon dioxide and water from respiration. This matters in Trophic levels in an ecosystem (biology only) because it supports the learning objective to explain how absorbed material is lost as waste, including carbon dioxide and water from respiration. Use respiration 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.

urea

urea is a curriculum-aligned term linked to the learning objective: Explain how absorbed material can be lost as urea in urine..

Explain

In Transfer of biomass, Explain means explain is a curriculum-aligned term linked to the learning objective: Explain how absorbed material can be lost as urea in urine. This matters in Trophic levels in an ecosystem (biology only) because it supports the learning objective to explain how absorbed material can be lost as urea in urine. Use Explain 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.

biomass transfer

biomass transfer is a curriculum-aligned term linked to the learning objective: Explain why large amounts of glucose used in respiration reduce biomass transfer..

glucose

In Transfer of biomass, glucose means glucose is a curriculum-aligned term linked to the learning objective: Explain why large amounts of glucose used in respiration reduce biomass transfer. This matters in Trophic levels in an ecosystem (biology only) because it supports the learning objective to explain why large amounts of glucose used in respiration reduce biomass transfer. Use glucose 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.

biomass transfer

biomass transfer is a curriculum-aligned term linked to the learning objective: Calculate the efficiency of biomass transfer between trophic levels using percentages..

efficiency

In Transfer of biomass, efficiency means efficiency is a curriculum-aligned term linked to the learning objective: Calculate the efficiency of biomass transfer between trophic levels using percentages. This matters in Trophic levels in an ecosystem (biology only) because it supports the learning objective to calculate the efficiency of biomass transfer between trophic levels using percentages. Use efficiency 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.

biomass transfer

biomass transfer is a curriculum-aligned term linked to the learning objective: Calculate the efficiency of biomass transfer between trophic levels using fractions of mass..

efficiency

In Transfer of biomass, efficiency means efficiency is a curriculum-aligned term linked to the learning objective: Calculate the efficiency of biomass transfer between trophic levels using fractions of mass. This matters in Trophic levels in an ecosystem (biology only) because it supports the learning objective to calculate the efficiency of biomass transfer between trophic levels using fractions of mass. Use efficiency 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.
