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.    

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
