    2929The other parameters (GC,,''i'',,, MO,,''i'',,) are already be entered or calculated in Ecopath, and the Q,,''ij'',, flows are calculated dynamically in Ecosim.  Ecotracer users can also enter inflow, outflow (dispersal/advection exchange to outside systems), and decay rates for the “environmental” (abiotic) concentration C,,''o'',,.

    31 When the Ecotracer simulation component is enabled (check box on Ecotracer entry form), Ecosim integrates the rate components listed above to generate time concentration patterns C,,''i'',, (,,''i'',,=0 to number of biomass pools), and time patterns of concentration per biomass C,,''i'',,/B,,''i'',, for all Ecopath/Ecosim biomass pools.  These results can be compared to data on bioaccumulation or tracer movement.  Discrepancies between model and data may help identify weaknesses in the ecopath/ecosim trophic flow rate (Q,,''ij'',,) estimates, and/or in the Ecotracer rate parameters (u,,''i'',,,e,,''i'',,,d,,''i'',,).
