Fungi do not make their own food. They depend on others for their food. On the basis of nutrition, there are three types of Fungi: Saprophytic, Parasitic and Symbiotic.
(1) Saprophytic: These types of fungi obtain their food from rotten organic matter, such as Rhizopus, Penicillium etc.
(2) Parasitic: Such fungi depend on other organisms for their food. These fungi are harmful. They cause diseases in both plants and animals. Astilago, Puccinia etc. are examples of this type of fungus.
(3) Symbiotic: Such fungi grow with other plants. They provide water and mineral salts to the plants and prepare food for them. Lichens are examples of this type of fungus.
