Food Chains: Producers and Consumers - KS3 Biology Worksheet

 A complete, no-prep 100-mark worksheet on food chains — ready to use for lessons, homework, or revision with KS3 Biology students aged 11-14.

These diagrams show how food passes from one living thing to the next, starting with a producer and moving through primary, secondary and tertiary consumers.

📝 Structured across three sections of progressive difficulty: Section 1 (30 marks) covers producers, consumers, photosynthesis, arrows and consumer levels through multiple choice, a true or false table and a word bank summary. Section 2 (40 marks) builds understanding through definitions, a grass, grasshopper, frog and heron table, writing a chain with arrows and short explanations. Section 3 (30 marks) challenges students with extended answers on a harvested wheat field, Britain's 1950s rabbit disease and predicting how more hawks affect snails. A full answer key with detailed marking guidance is included. Comes as a PDF and an editable Word file (DOCX).
