Nutrition is the biochemical and physiological process by which an nutritional value of bell peppers uses food to support its life. The type of organism determines what nutrients it needs and how it obtains them. Organisms obtain nutrients by consuming organic matter, consuming inorganic matter, absorbing light, or some combination of these.

Some can produce nutrients internally by consuming basic elements, while some must consume other organisms to obtain pre-existing nutrients. Scientific analysis of food and nutrients began during the chemical revolution in the late-18th century. Chemists in the 18th and 19th centuries experimented with different elements and food sources to develop theories of nutrition. Modern nutrition science began in the 1910s as individual micronutrients began to be identified. Composting within agricultural systems capitalizes upon the natural services of nutrient recycling in ecosystems.
