The source of carbon for the Calvin cycle is carbon dioxide.
Carbon dioxide
carbon dioxide is used in the Calvin cycle.
The Calvin cycle is called such because every process produces something that the next process needs, right back to the original step. Carbon fixation produces the molecules needed for reduction, which produces the molecules needed for the regeneration of ribulose, which produces what's needed for carbon fixation.
During photosynthesis, light energy is used in generating chemical free energy, stored in glucose. The light-independent Calvin cycle, also known (erroneously) as the "dark reaction" or "dark stage," uses the energy from short-lived electronically-excited carriers to convert CO2 and water into organic compounds that can be used by the organism (and by animals that feed on it).

Carbon dioxide
RuBP: Ribulose Biphosphate It is a 5-carbon molecule which combines with carbon dioxide in the Calvin cycle to produce a six-carbon compound. Hope this helps!

The Calvin cycle, or carbon fixation, occurs during the dark reactions of photosynthesis.
During photosynthesis, light energy is used in generating chemical free energy, stored in glucose.

The Calvin cycle takes place in the stroma of the chloroplast. Carbon dioxide enters the stroma of the chloroplast to combine with the five-carbon compound called ribulose1, 5-Biphosphate to form two molecules of a three-carbon compound called 3-Phosphoglyceric acid. This reaction is catalyzed by an enzyme called Ribulose bi-phosphate Carboxylase.
