The values of biological parameters calculated per 1 g C-org. were generally 0.5 to 2 orders of magnitude higher in the water than in the sediments. The exceptions were biomass (Ba), production (P), and respiration (Ra) of algae, approximately 0.5 to 1 order of magnitude higher in the sediments of the stream and respiration of bacteria (Rb) to their biomass (Bb) 0.7 order of magnitude higher in sediments of the dam reservoir.
