Fungi are eukaryotic organisms. Many fungi are saprophytic, meaning they derive their nutrients from other dead organisms. Thus, fungi are an important role in the ecosystem as decomposers and tend to break down other dead organisms.
Answer and Explanation:
Fungi can be unicellular or multicellular. Unicellular organisms are made of a single cell and are microscopic. An example of a unicellular fungi is yeast, like the type we use in making bread and beer. Multicellular organisms are made of more than one cell and their cells are often differentiated into tissues and organs to allow the organism to carry out many different biological processes. An example of a multicellular fungi is mushrooms or the mold we see growing on our food.
