Q

What are three factors that affect the rate of decomposition?

A

Temperature. At warm temperatures, the enzymes used by microorganisms are at their optimum, meaning there will be a faster rate of decomposition.
Moist environments. The greater the volume of water available, the faster the rate of decomposition.
Oxygen. Aerobic conditions available mean that there will be a greater rate of decomposition.
