<human>:  Why is it called the Kingdom Fungi?
<bot>: That’s a good question. The name comes from the Latin word fungus, which means “little mushroom”. In the Kingdom Fungi, fungi are the most important organisms, because they are the most abundant source of organic matter on Earth. Fungi are also important because they are responsible for the decomposition of dead plant material. Fungi are also important because they are the producers of antibiotics and other pharmaceuticals.
