Fungi cannot make their own food is the statement that BEST describes why mycelium, constructed of hyphae, are necessary for fungi survival.
Mycelium are the vegetative part of any fungus, consisting of a mass of branching, threadlike hyphae, usually found under the ground or inside the substrate on which the fungi are growing. The large masses of hyphae within the mycelium perform an essential role by obtaining nutrients from the organic substrates in which the fungi live or from beneath the soil to support fungi growth and its survival. This is because fungi do not have chlorophyll and cannot manufacture their own food.
