During what cycle are sugars produced in the chloroplast

The Calvin cycle is the cycle where in sugars are produced in the chloroplast. Calvin cycle is also known as the Calvin-Benson cycle. Calvin cycle has three stages this is fixation, reduction, and regeneration.  Calvin cycle is needed in Photosynthesis.    

The carbon in the air will lessen over time. This is because it is being trapped in the walls of the biodome. This will affect living things negatively as the carbon cycle is a necessary part of nature and throwing off the balance of carbon in the carbon cycle will throw off the balance of the entire ecosystem within the biodome.
