Question 1 · 1 mark · Difficulty 1/3

Which trophic level do primary producers occupy in a food chain?

  1. Trophic level 1
  2. Trophic level 3
  3. Trophic level 4
  4. Trophic level 2
Show answer & explanation
✓ Answer: A — Trophic level 1
Primary producers, such as plants and algae, occupy trophic level 1 because they produce biomass through photosynthesis. They form the base of all food chains and food webs.
Question 2 · 1 mark · Difficulty 1/3

In a food chain, a secondary consumer eats a primary consumer. At which trophic level is the secondary consumer?

  1. Trophic level 4
  2. Trophic level 1
  3. Trophic level 2
  4. Trophic level 3
Show answer & explanation
✓ Answer: D — Trophic level 3
Producers are at trophic level 1, primary consumers at level 2, and secondary consumers at level 3. The secondary consumer feeds on the primary consumer, placing it one level above.

AQA GCSE Biology: Trophic levels and biomass transfer FAQ

Is Kramizo free for AQA GCSE students preparing for Biology?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix Trophic levels and biomass transfer practice with other Biology topics or even switch to a totally different AQA subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the Trophic levels and biomass transfer questions aligned to the official AQA GCSE Biology syllabus?
Every question is written against the published AQA GCSE Biology specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real AQA paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from AQA.
How is Trophic levels and biomass transfer typically tested on AQA GCSE Biology papers?
Trophic levels and biomass transfer appears across multiple question types on real AQA GCSE Biology papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
