Carbon dioxide
Carbon dioxide, can be represented with the chemical formula CO2 as it is formed by two Oxygen atoms covalently linked to a central Carbon atom.
Carbon dioxide is essential for the process of photosynthesis which occurs in the chloroplasts of plants. This is a process in which the carbon dioxide from the air (around 0.0360% of the air is carbon dioxide)[1]: produced by respiration by living organisms, as well as by the combustion of fossil fuels, is utilised by the plants to produce the sugars they require to grow.
