Using the radioisotope method, new quantitative characteristics of the role of phytoplankton in the formation of the pool of dissolved organic substances (ROS) in the freshwater ecosystem were obtained. The destruction of dead phytoplankton is carried out within one week. In natural reservoirs, detritus settles at a rate of about one meter per day. In deep reservoirs, most of the MOAT is released in the water column rich in oxygen, where it is destroyed by bacterioplankton. In shallow reservoirs (such as fish ponds), detritus particles do not have time to decompose in the water column. Their further destruction is carried out at the bottom of the reservoir when there is a lack of oxygen, which leads to overseas phenomena.
