Nutrition is the process by which an organism takes food and utilizes it to get energy, for growth, repair, maintenance, etc. and then excreting the waste material from the body. The materials which provide nutrition to living organisms are called nutrients. For example proteins, carbohydrates, vitamins, etc.Types of Nutrition:1. Autotrophic Nutrition: \tAutotrophic nutrition is the mode of nutrition in which an organism prepares its own food.\tBlue-green algae and Green plants follow the autotrophic mode of nutrition.2. Heterotrophic Nutrition:\tThe mode of nutrition in which an organism takes food from another organism is called Heterotrophic mode of nutrition.\tOther than green plants and blue-green algae organisms show the heterotrophic mode of nutrition.\tHeterotrophic nutrition can be further categorized into two types, viz. saprophytic nutrition and holozoic nutrition.3. Saprophytic Nutrition:\tIn the saprophytic mode of nutrition; the organism secretes the digestive juices on the food. The food is digested while it is still to be ingested.\tThe assimilated food is then consumed by the organism. All the decomposers follow saprophytic nutrition. Some insects; like houseflies; also follow this mode of nutrition.4. Holozoic Nutrition:\tIn holozoic nutrition; the digestion happens inside the body of the organism, i.e. after the food is ingested. Most of the animals follow this mode of nutrition.
