We investigated the magnitude and intensity of phosphorus turnover and energy flows in the plankton and zoobenthos communities of a shallow, highly eutrophied reservoir. Due to a high degree of reservoir eutrophication, the energy flow through zooplankton significantly exceeded energy flow through zoobenthos. The role of biota in the phosphorus turnover was very high. During the growing season, plankton organisms regenerated 1.5 times more phosphorus than the external load per year, and five times more than the internal load of this element. Maximum value of primary plankton production was observed in the year with the highest rate of phosphorus turnover.
