In this Class 10 Science topic from the chapter Life Processes, students learn how organisms obtain and use food for energy, growth, repair, and maintenance. The topic introduces autotrophic nutrition in plants, including photosynthesis and the role of chlorophyll, sunlight, carbon dioxide, and water, as well as heterotrophic nutrition in animals. Students also study human nutrition through the digestive system, the functions of digestive organs and enzymes, absorption of nutrients in the small intestine, and the importance of a balanced diet.
