Explanation:

Fungi are eukaryotes and have saprophytic mode of nutrition. They decompose dead and decaying matter and breakdown complex organic molecules to simple inorganic nutrients for consumption. Hence, they play a very important role in any food chain.

Fungi are very diverse in their morphology. They can be unicellular like yeast or multicellular and filamentous like moulds. The long branched filaments are called hyphae. Hyphae form a tangled network called as mycelium. Hyphae have a cell wall and an inner lumen. Lumen can either be septate i. e. it is divided into compartments or coenocytic i. e. protoplasm freely flows through it.
