Nutrition—Types of Nutrition

This topic categorises nutrition in living organisms into autotrophic and heterotrophic modes, with further classification of heterotrophic nutrition (parasitic, saprophytic, holozoic). It aligns with the Zambian CBC by enabling learners to relate nutrition to organisms in their local environment. Mastery is essential for ECZ questions on feeding relationships, ecosystems, and biological diversity, building a foundation for exam success and ecological understanding.
