Energy and Nutrition

The video explains that all living things, from microorganisms to large animals, require energy to perform essential functions. Plants obtain energy through photosynthesis, converting sunlight, carbon dioxide, and water into sugars. Organisms that do not photosynthesize must consume other organisms to meet their energy needs. The video also discusses the importance of nutrients in food, which provide energy and support bodily processes, and the study of nutrition, which examines how the body uses food to maintain health.
