Human nutrition — IGCSE Biology (0970) questions by topic
Human nutrition questions calculate nutrient content per serving from a yoghurt data table, identify dentine's position in a labelled tooth diagram, state where water is absorbed along the gut, and identify which organ stores bile.
Choose, state, identify, describe and draw span 1 to 24 marks, the widest range in this Biology set, across 75 real questions from 2023 to 2025 papers. Because nutrient calculations depend on reading table values accurately before any arithmetic begins, submitting a worked answer for instant marking catches a misread figure or a rounding slip the moment it happens rather than after several dependent steps.
