Materials Cycle.
Energy Does Not.

GCSE Biology Knowledge Mat — Ecosystems (PDF)

Why carbon goes round for ever while energy passes through once — and what that forces every food chain to look like. Organism to ecosystem, abiotic and biotic factors; the carbon and water cycles and what stops decay; biomass falling at every trophic level, with a worked efficiency calculation; coral reefs, permafrost and irrigated farmland under pressure. Twelve terms to define, a model answer on why food chains are short, and the misconceptions that cost marks.

    Cover of Materials Cycle. Energy Does Not.

    One landscape A4 page on one topic, led by the figures and photographs rather than the headings. It carries the levels of organisation, the carbon and water cycles, biomass loss between trophic levels with a worked efficiency calculation and three ecosystems under pressure — then the vocabulary, a worked exam-style answer and the misconceptions that cost marks.

    Every photograph on the sheet is a real archival or scientific image, not an illustration and not AI-generated; every diagram is drawn in code for the sheet. Each image was checked against its own licence template rather than a label, and the running foot names every creator, states that the images have been cropped and adjusted for print, and links the licence — so the sheet can be photocopied for a class and stay compliant. Every claim is sourced to the DfE subject content, and nothing is reproduced from a past paper, a textbook or a specification.

    Sold by subject: all four biology sheets for one price. A knowledge organiser stores a unit and is revised from afterwards; this is meant to be on the table while the work is happening.

    Written to
    The DfE GCSE subject content for biology (DFE-00351-2014). Every photograph is a sourced archival or scientific image, licensed for reuse and credited on the sheet; every diagram is drawn in code for the sheet
    Intended for
