Each visit shows a fresh randomly-picked question from the live CIE IGCSE Co-ordinated Science (Double Award) bank, so you can keep refreshing to try different ones before deciding whether to create a free account for daily access.

Q: Is Kramizo really free for CIE Co-ordinated Science (Double Award) students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Co-ordinated Science (Double Award) questions aligned to the CIE IGCSE syllabus?

Every question is written against the published CIE IGCSE Co-ordinated Science (Double Award) syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real CIE past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

A pyramid of numbers for a woodland ecosystem has a very wide base and a very narrow top. What does the wide base most directly represent?

Accepted Answer

A large number of organisms at the producer level — A pyramid of numbers represents the number of individual organisms at each trophic level; therefore a wide base indicates a large number of individual producers such as grass plants. Option A describes a pyramid of energy, not numbers. Option C describes a pyramid of biomass. Option D refers to species diversity, which is not what a pyramid of numbers shows.

Answer

A large number of organisms at the producer level

Answer

A large biomass of organisms at the producer level

Answer

A large number of species at the producer level

Answer

A large amount of energy stored at the producer level
