A proportion of this lost as respiratory heat (R) 9 of 14 Net primary production (NPP) actual rate of production of new biomass available for consumption by heterotrophs, production remaining after redpiration. 10 of 14 secondary productivity Rate of production of biomass by heterotrophs 11 of 14 Catabolism enzymatic degradation of a compound from a polymer to a monomer (e.g. cellulose to glucose) or to its mineral constituents (glucose to CO2 and H2o) 12 of 14 Comminution Physical reduction of a particle size by animal feeding or abiotic factors 13 of 14 Leaching physical removal of soluble materials by water. Leaching is influenced by catabolism and comminution 14 of 14
