. "Climate and Forecast (CF)" . . "\"Respiration carbon\" refers to the rate at which biomass is respired expressed as the mass of carbon which it contains. Heterotrophic respiration is respiration by heterotrophs (\"consumers\"), which are organisms (including animals and decomposers) that consume other organisms or dead organic material, rather than synthesising organic material from inorganic precursors using energy from the environment (especially sunlight) as autotrophs (\"producers\") do. Heterotrophic respiration goes on both above and within the soil. In accordance with common usage in geophysical disciplines, \"flux\" implies per unit area, called \"flux density\" in physics." .
