If carbon dioxide is completely removed from a plant's environment, the process of photosynthesis would stop, and the production of high-energy sugars will cease as a result.
During photosynthesis, inorganic molecules in the forms of water and carbon dioxide are used to synthesize high-energy sugar in the presence of sunlight. The equation of the reaction can be summarized as follows:
[tex]6CO_2 + 6H_2O ---> C_6H_{12}O_6 + 6O_2[/tex]
Hence, without the presence of carbon dioxide, the process will be halted and the production of high-energy sugar in the form of glucose will also stop.
