Fig. 2. Schematic diagram of a cell of the model considering the distribution 

 of the elements of a pelagic ecosystem: J--solar radiation; P--biomass of 

 phytoplankton; Pp--production of phytoplankton; n--concentration of nutrients; 

 b--biomass of protozoa; f2--biomass of microzooplankton; f3--biomass of fine 

 filter feeders; f4--biomass of coarse filter feeders; si--biomass of cyclopoids; 

 S2--biomass of carnivorous calanoids; S3--biomass of chaetognaths and polychaetes. 

 DOM--dissol ved organic matter. Remaining symbols same as in Figure 1.
