Definition: Nutritory is a term used in nutritional science to describe an organism that has a high level of energy and nutrients. It refers to a type of organism that can extract all the necessary nutrients from its environment, including water and food. Nutritories are often found in aquatic organisms such as fish, crustaceans, and certain types of bacteria.
