Photosynthesis. Plants and photosynthetic algae and bacteria use energy from sunlight to combine carbon dioxide (C0 2) from the atmosphere with water (H 2 O) to form carbohydrates. These carbohydrates store energy. Oxygen (O 2) is a byproduct that is released into the atmosphere.This process is known as photosynthesis.. Carbon dioxide is removed from the atmosphere by dissolving in water and forming carbonic acid. 2. Carbonic acid is used to weather rocks, yielding bicarbonate ions, other ions, and clays. 3. Calcium carbonate is precipitated from calcium and bicarbonate ions in seawater by marine organisms like coral.
Some CO 2 is obtained from the combustion ofcoke or other carbon-containing fuels.C(coke) + O 2 (g) xxv CO 2 (g)Carbon dioxide is released into our atmosphere when carbon-containing fossil fuels such as oil, natural gas,and coal are burned in air.
