Some solid substances, like fats, waxes, and sugars, may melt and separate. Between 100 and 500 °C, many common organic molecules break down. Most sugars start decomposing at 160–180 °C. Cellulose, a major component of wood, paper, and cotton fabrics, decomposes at about 350 °C. [3]
Additionally, [3] soil animals are considered key regulators of decomposition at local scales but their role at larger scales is unresolved.
