Fungus

A fungus is any eukaryotic organism that includes microbes like yeasts and moulds, as well as the more recognisable mushrooms. These organisms are classed as a kingdom distinct from the other eukaryotic kingdoms, which include Plantae, Animalia, Protozoa, and Chromista in one traditional taxonomy.

The presence of chitin in fungi's cell walls distinguishes them from plants, bacteria, and some protists. Fungi, like animals, are heterotrophs; they obtain nourishment by absorbing dissolved molecules, usually by secreting digestive enzymes into their surroundings.

Fungi, like plants, use chemical defence, which involves the creation of poisons that affect the growth, development, or viability of the antagonists.
