Carbon cycle processes in terrestrial ecosystems. The abbreviations of items used in the figure were as below: GPP (gross primary productivity), Ra (autotrophic respiration), Rh (Heterotrophic respiration), ER (ecosystem respiration), ERC (emission from reactive carbon), ECI (emission from creature ingestion), CRC (carbon removal from cropland), CRG (carbon removal from grassland), CRF (carbon removal from forest), EF (emission from fire), Ewin (emission from wind erosion), Ewat (emission from water erosion), EAD (emission from anthropogenic disturbances), END (emission from natural disturbances), HC (human returned carbon), IF (industrial fertilizer). The figure was made with Microsoft Powerpoint 2010 (https://products.office.com/en-us/powerpoint). All individual images were taken by ourselves.
