Saprophytic nutrition is a type of heterotrophic nutrition where organisms obtain their nutrition by feeding on dead or decaying organic matter, such as dead plants or animals. These organisms are known as saprophytes or decomposers. 

They secrete digestive enzymes that break down complex organic matter into simpler compounds such as carbon dioxide, water, and mineral ions, which can then be absorbed and used as a source of energy and nutrients by the saprophytic organisms.
