The provided diagram illustrates the process of producing the biofuel, ethanol.
Overall, there are 7 stages in producing ethanol, beginning with harvesting the plants and crops, ending with adding microbes and using it for transportation. Sunlight and carbon dioxide are the main energy sources for the growth of plants and trees. Once the plants are fully grown, they are harvested using a special machine known as a pre-processor. The next stage involves putting to cellulose, so that they can be wrapped.
However, after that, it undergoes processes such as chemical transformations. Subsequently, sugars and microbes are added, from which the ethanol is produced. These give special mixture for biofuel. Also, it is used for transportation which emitts carbon dioxide from plans, trucks, and cars, that relieves to air. Finally, the ethanol is used for transportation in vehicles such as planes, trucks, and cars, which emit carbon dioxide into the atmosphere.
