Nutrition

An organism uses food to sustain its existence through a biochemical and physiological process known as nutrition. It gives living things nutrition that can be processed to produce energy and chemical building blocks. Malnutrition results from insufficient dietary intake. Although it frequently focuses on human nutrition, nutritional science is the study of nutrition.

What nutrients an organism requires and how it gets them depends on the type of creature. Consuming organic or inorganic material, absorbing light, or a mix of these is how organisms gain nutrition. While some must devour other species in order to receive preexisting nutrients, others may manufacture nutrients internally by ingesting fundamental materials.

All living forms require several chemicals, including carbon, energy, and water. Animals need complex nutrients like proteins, lipids, and carbohydrates, and they get them by eating other living things. For the purpose of replacing foraging and improving human nourishment, humans have created agriculture and cooking. Nutrients are provided to plants by the soil and the environment. Through the mycelium, fungi break down and take up nutrients from their surroundings.
