Explain the Nutrition of Fungi?

Fungi grow in moist environment and are chemoorganoheterotrophs. What do we mean by chemoorganoheterotrophs? The term chemotroph describes organism that generate energy by oxidation of organic or inorganic compounds. Chemoorganoheterotrophs use organic compound as a source of energy, electron and carbon. Most of the fungi grow on dead organic matter by producing exoenzymes. These are saprophytes. Few fungi are parasitic. Fungi are usually aerobic though some are anaerobic e.g., as in rumen of cattle. Yeasts are mostly facultative anaerobes (i.e., they can survive either in the presence or absence of oxygen).
