WebThey form when an organism dissolves into the earth and leaves behind a hollow mold. The cavity that forms on the sediment is a carbon film containing so-called body fossils. Molten fossils are formed if the mold blanks are subsequently filled with minerals. WebSoil organisms play a vital role in the degradation of organic matter and subsequent soil humus formation. When plants die, leaves are dropped onto the soil surface where microorganisms can “attack” and decay plant tissue. The organic matter is used as an energy source for microorganisms, increasing their population in the soil.
