ABSTRACT

The scale of production-destruction biotic balance in the Black Sea ecosystem, flows of organic carbon, carbon dioxide, and oxygen, and rate and volume of organic matter input in the Black Sea sediment as a source of formation and accumulation of fossilized hydrocarbon fuel minerals are estimated on the basis of the current concept of efficiency of solar radiation utilization by photosynthesis. The volume of "excessive" oxygen formed in the ecosystem and its contribution to global oxygenation of the atmosphere are shown.
