explain the process of carbon fixation
Carbon Fixation. Carbon fixation is a process found in autotrophs (organisms that produce their own food), usually driven by photosynthesis, whereby carbon dioxide is changed into organic materials.Carbon fixation can also be carried out by the process of calcification in marine, calcifying organisms such as Emiliania huxleyi.n plants, there are three types of carbon fixation during photosynthesis: C3 â a plant that uses the Calvin Cycle for the initial steps that incorporate CO2 into organic matter, forming a 3-carbon compound as the first stable intermediate. Most broadleaf plants and plants in the temperate zones are C3.
