The Primary Crop of Phytoplankton and Total Organic Matter Destruction in Varvara Reservoir, One of the Main Reservoirs of Azerbaijan

The role of phytoplankton in regulating the flow of physico-chemical processes in ecosystems, including hydrobionts, which is involved in the formation of biological products, the circulation of substances in the life of reservoirs, the creation of their energy source, is very large. Fhytoplankton ecosystems are very sensitive to abiotic factors and anthropogenic influences to many physical, chemical and biological factors present in the environment. Therefore, phytoplankton is considered the basis of trophic relationships in the hydroecosystem.
