The fungi that consume dead and decayed organic matter directly as food are known by which of the following options?

Fungi (plural: fungus) are a kingdom of multicellular eukaryotic organisms that are heterotrophs (cannot produce their own food) and play important roles in ecosystem nutrient cycling. The majority of fungi are decomposers. They eat decayed organic debris and return nutrients to the soil for plants to use. Fungi are the most important decomposers in forests because they are the only organisms capable of decomposing both wood and the cellulose found in plant cell walls.
