Figure 6

Schematic view of the integration of main OM sources by primary consumers, through fatty acid trophic markers. The relative importance of such integration is indicated by arrows (from dotted lines for minor role, to thick lines for important role). POM: particulate organic matter, SOM: sedimentary organic matter, DTP: detrital terrestrial plant material. For OM pools (POM and SOM), the % indicate the relative importance of primary producers (bacteria, phytoplankton, DTP etc.) assessed by major FAs trophic markers.
