Like all other living Organisms, Fungi too need food, water, and oxygen to survive. Fungi cannot synthesize their own food, it intakes through thin root-like outer walls called hyphae. Through hyphae, the food, water, and oxygen enter into the living fungal cell through the process of absorption. Fungi are heterotrophic and depend on other Organisms for living. Like other animals, the Fungi can extract energy in the form of sugar and Protein from organic and inorganic compounds.
