This document discusses the differences between living and non-living things. It notes that people, animals and plants are living things that need food, water and air to survive. They are born, grow, reproduce and eventually die. In contrast, non-living things like rocks, sand, air and man-made objects do not have these characteristics of life. The document also describes how living things like eggs, tadpoles and seeds change forms as they grow and develop. Plants and domesticated animals are highlighted as being important to humans by providing food, materials and other resources.
