They're microscopic organisms containing enzymes (responsible for digesting and decomposing) and spores (in charge of reproduction). Mold dwells within the fungi kingdom: a realm that includes mushrooms, yeast and other seemingly unsavory characters. Simply the truth is, these decay organisms aren't unsavory at all. Without them, toppled trees, dead animals and fallen vegetables wouldn't decompose. Our land would get piled higher and higher with dead stuff.
