Detailed explanation-1: -Carbon fixation is the process wherein photosynthetic organisms (such as plants) turn inorganic carbon into organic compounds (carbohydrates). CO2 fixation, for instance, is a type of carbon fixation wherein carbon dioxide from the atmosphere is converted into carbohydrates.

Detailed explanation-2: -Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

Detailed explanation-3: -The number of carbon atoms remains the same, as the atoms move to form new bonds during the reactions (3 atoms from 3CO2 + 15 atoms from 3RuBP = 18 atoms in 3 atoms of 3-PGA). This process is called carbon fixation, because CO2 is “fixed” from an inorganic form into an organic molecule.

Detailed explanation-4: -Biological carbon fixation or arbon assimilation is the process by which inorganic carbon (particularly in the form of carbon dioxide) is converted to organic compounds by living organisms. The compounds are then used to store energy and as structure for other biomolecules.
