Carbon dioxide doesn't form in the Calvin Cycle (I assume you're referring that because there isn't such a thing as the "Calving Cycle" in biochemistry. Carbon dioxide must be taken in by the plant via the stomata and it is then used by the plant in photosynthesis. Clearly, this is why plants rely on carbon dioxide to complete the Calvin cycle and in large, photosynthesis.

The Processes Of Photosynthesis And Cellular Respiration Form Carbon Dioxide-Oxygen Cycle
The Calvin cycle uses carbon from carbon dioxide (CO2) to form carbohydrates.
Carbon form carbon dioxide by oxydation.
Carbon dioxide absorbed in water form a carbonic acid.
Plants remove Carbon Dioxide from the environment.
The Processes Of Photosynthesis And Cellular Respiration Form Carbon Dioxide-Oxygen Cycle
carbon dioxide
It breathes out carbon in a form of carbon dioxide.
The two processes of the carbon cycle are photosynthesis and cellular respiration. In photosynthesis carbon from carbon dioxide is fixed into carbohydrates. In cellular respiration, carbohydrates are broken down to form ATP and carbon in the form of carbon dioxide is released into the atmosphere.
Carbon dioxide gas.
In the atmosphere, they are attached in the form of gaseous carbon dioxide (CO2).
A byproduct of the krebs cycle/citric acid cycle is carbon dioxide.
G3P molecules which combine to form glucose
Calvin Cycle :}
When carbon reacts with oxygen to form carbon dioxide, carbon dioxide is the product of the reaction.
During photosynthesis carbon from carbon dioxide is synthesized in to more complex organic compounds and in respiration it is again released in the form of carbon dioxide gas. Thus both these processes play important role in carbon cycle.
The Calvin cycle uses carbon from carbon dioxide (CO2) to form carbohydrates.
