The image demonstrates how a natural fuel known as ethanol is manufactured.
Overall, it is evident that the ethanol content takes steps to manufacture it properly. In the initial step, it needs the energy combined of sunlight and carbon dioxide, which eventually comes from the vehicles at the end.
To begin with, to grow plants and trees, it needs sunlight and carbon dioxide. After plants as well as trees grow, it goes to harvesting, which later put into the processing machine. It cut down the harvested crops into a smaller form. They are then drawn into the cellulose, which further takes part in the chemical reaction. After completing the chemical processing, it is converted into sugar, the sugar which is produced, combined with the microbes, and then the ethanol is formed.
Secondly, after manufacturing ethanol, it is used in vehicles like car, truck, along with airplanes, which runs through biofuel. Then,these vehicles throw carbon dioxide, which later mixed in atmosphere. Due to this, the cycle remain same.
