Transformations of inorganic molecules that lead to the production of N2O (nitrification and denitrification), as well as the consumption of CH4 (methanotrophy) are classified as Biochemical transformations because these processes involve conversions of, rather than breakdown of molecules. Nitrification and denitrification are included here, as well as in the Nutrient Cycling model, because they are the most relevant N cycle processes that control N2O emissions. All three processes supporting Biochemical transformations are performed by micro-organisms.
Rates of processes that Biochemical transformations depend on the availability of resources.
