Food is any nutrient-rich material eaten by plants and animals in order to sustain life and promote growth. Most organisms obtain their food from other living organisms or organic matter. Plants make their own food through photosynthesis, while animals acquire it by eating other animals or plants or by consuming other substances. Humans have evolved many techniques for preserving, storing, and cooking food.
