Nutritional value of avocado
On this Wikipedia nutritional value of avocado language links are at the top of the page across from the article title. Nutrition is the biochemical and physiological process by which an organism 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. Nutrients are substances that provide energy and physical components to the organism, allowing it to survive, grow, and reproduce.
Nutrients can be basic elements or complex macromolecules. Nutrients are absorbed by the cells and used in metabolic biochemical reactions. Organisms can be classified by how they obtain carbon and energy. Heterotrophs are organisms that obtain nutrients by consuming the carbon of other organisms, while autotrophs are organisms that produce their own nutrients from the carbon of inorganic substances like carbon dioxide.

In nutrition, the diet of an organism is the sum of foods it eats. A nutrient cycle is a biogeochemical cycle involving the movement of inorganic matter through a combination of soil, organisms, air or water, where they are exchanged in organic matter. Biogeochemical cycles that are performed by living organisms and natural processes are water, carbon, nitrogen, phosphorus, and sulfur cycles. Foraging is the process of seeking out nutrients in the environment. It may also be defined to include the subsequent use of the resources. Some organisms, such as animals and bacteria, can navigate to find nutrients, while others, such as plants and fungi, extend outward to find nutrients.
Foraging may be random, in which the organism seeks nutrients without method, or it may be systematic, in which the organism can go directly to a food source. Nutrient deficiencies, known as malnutrition, occur when an organism does not have the nutrients that it needs. This may be caused by absorbing insufficient nutrients or by suddenly losing nutrients. When this occurs, an organism will adapt by reducing energy consumption and expenditure to prolong the use of stored nutrients.
Animals are heterotrophs that consume other organisms to obtain nutrients. Herbivores are animals that eat plants, carnivores are animals that eat other animals, and omnivores are animals that eat both plants and other animals. All macronutrients except water are required by the body for energy, however, this is not their sole physiological function. The energy provided by macronutrients in food is measured in kilocalories, usually called Calories, where 1 Calorie is the amount of energy required to raise 1 kilogram of water by 1 degree Celsius. Carbohydrates are molecules that store significant amounts of energy. Animals digest and metabolize carbohydrates to obtain this energy. Carbohydrates are typically synthesized by plants during metabolism, and animals have to obtain most carbohydrates from nature, as they have only a limited ability to generate them.
