They don't.
The Calvin cycle is a carbon dioxide gas from the atmosphere and the energy carried by ATP and NADPH to make simple sugars.

Carbon is used to make sugars in the "carbon fixation" step of the carbon cycle, which occurs during photosynthesis in plants. During this process, carbon dioxide from the atmosphere is converted into organic sugars, which are used for energy and growth by plants.
In the carbon dioxide-oxygen cycle, plants take in carbon dioxide during photosynthesis and release oxygen as a byproduct. Animals then consume this oxygen and release carbon dioxide as a waste product during respiration. This cycle maintains a balance of oxygen and carbon dioxide in the atmosphere essential for life on Earth.
The carbon cycle begins with photosynthesis in plants because plants take in carbon dioxide from the atmosphere during photosynthesis to produce glucose, which forms the basis of their energy and growth. This process converts atmospheric carbon dioxide into organic carbon, making it available for the rest of the ecosystem.
The Calvin cycle is a part of photosynthesis where carbon dioxide from the atmosphere is converted into glucose, a carbon-based molecule. This glucose, along with other carbohydrates produced in the Calvin cycle, serves as the main energy source for plants. When you eat plants or plant-based foods, you consume these carbon-based molecules, which are then used by your body for energy and building blocks in cellular processes.
The gas in air used by plants to make food is carbon dioxide. Plants use carbon dioxide during the process of photosynthesis to convert energy from sunlight into glucose, which is used as a source of energy and growth.
There are many similarities, as well as differences. However, I think the main point would be, that if we only look at the larger picture and not the particular steps of the cycles, the two can be thought of as being a reversal of each other. The Calvin cycle captures carbon dioxide to make organic molecules. The Krebs cycle breaks down organic molecules to produce energy - and releases carbon dioxide in the process.
No, carbon dioxide is used during photosynthesis. It is necessary for the Calvin-Benson cycle because it is attached to RuBP to start the cycle. This cycle ultimately produces glucose. However, carbon dioxide is made as a by-product of cellular respiration.
