Maintenance of the Organism

This unit focuses on how organisms maintain themselves through nutrition. Students will classify food nutrients, apply good eating practices for different groups, categorise plant nutrients, and learn about nutritional deficiency diseases. This knowledge connects biology directly to personal and public health, a key aspect of the Zambian CBC. It prepares learners for ECZ questions on human biology, diet, and health, fostering an understanding of how organisms obtain and use energy and materials.
