The article considers the model of the global carbon cycle, in which photosynthesis is one of the key elements. The model itself is considered as the transition of carbon from the oxidized state to the reduced one and back. This transition is carried out by photosynthesis. The main oxidation of sedimentary organic carbon and its transition to an oxidized form is carried out by means of a natural reaction of thermochemical sulfate reduction, which occurs in the subduction zone (the zone of collision of lithospheric plates). A number of natural facts substantiating some key provisions of the model are given.
