Fungi are not producers. A producer "produces it's own food" or more specifically, it creates organic molecules from inorganic molecules using a nonliving energy source. Fungi are consumers because they "consume another organism for food" or more specifically they steal organic molecules from other living things.
No. Fungi are decomposers. A producer, makes its own food. A fungus does not make its own food, it breaks down nutrients from dead organisms to get a part of what it needs to survive. Which is why it is called a decomposer.
