It is demonstrated that the equation for photosynthesis in large systems can be transformed to the customary form employed in the analysis of a single photosynthesizing organism of type C-3, and that the equation describes the same photosynthesis traits that are inherent in these organisms. However, photosynthesis in big systems has two distinct characteristics as a result of its participation in such systems. There are two characteristics that distinguish global photosynthesis in the carbon cycle from traditional photosynthesis. The first is photosynthetic evolution's pulsation nature, which explains the recurrence of many phenomena in the biosphere, such periodic changes in "greenhouse" effects and glaciations, mass extinctions of life, climatic cycles, biotic turnover, and so on. The second feature is the global photosynthesis's spontaneous ascent to the ecological compensation point. It determines the global carbon cycle's shift to a stationary state. This trait enables researchers to comprehend how sedimentary organic matter accumulated in the earth's crust and oxygen accumulated in the atmosphere. When the ecological compensation point is reached, a stationary state of the carbon cycle emerges, the carbon balance in the system can be assessed.
