The importance of organic molecules cannot be over emphasized. It is very important to living organisms as it contains the most important elements which include; protein, carbohydrates, lipids, nucleic acids.

These elements are very crucial and important to our survival on earth(both plants and animals) . The factor which is responsible for the reduction in the amount of organic molecules is the increase in the amount of oxygen production. A lot of plants today contribute to this factor as they produce high amount of oxygen as their waste product.

Hence, the reason for the absence of organic molecules on earth is because it contains protein, carbohydrate, lipids, nucleic acids.
