There are 3 main processes that carbon dioxide (co2) must go through :
Respiration - All plants and animals are able to release energy from their food using respiration. This can also include any other living organism out there.
Combustion - This is the process of burning fuel. This releases carbon dioxide into the open space.
Photosynthesis- Any sort of g<span>reen plant, such as flowers, can remove carbon dioxide from the atmosphere by using photosynthesis. </span>
For example, the ABO system of blood groups is controlled by three alleles, only two of which are present in an individual.
