Revise AQA GCSE Biology 7.2.2 How materials are cycled with the question bank, lessons, revision guides, and flashcards.

Water is continuously evaporated and precipitated. • Students should be able to explain the role of microorganisms in cycling materials through an ecosystem by returning carbon to the atmosphere as carbon dioxide and mineral ions to the soil.
