Biofuels and the Carbon Cycle The carbon cycle is the process by which carbon molecules are added to the atmosphere and then removed by the natural processes of the earth. Carbon Cycle Basics Oceans and rivers absorb carbon in the atmosphere. Plants also absorb carbon during photosynthesis and convert it to oxygen. Animals use the oxygen produced by plants and convert it back to carbon dioxide. CH4 (Burp) Climatekids.nasa.gov Burning fossil fuels in cars and factories also releases carbon back into the atmosphere. Biofuels Basics Biofuels are fuels made from organic matter — like plants. Burning organic matter, or biomass, can produce energy. The biofuels process recycles carbon. Burning biomass does not add any new carbon to the atmosphere. It releases the carbon that was already absorbed by plants used to make the biofuels back into the atmosphere and then it is used again by new plants.
