The diagram illustrates the different process of how biofuel called ethanol is produced.
Overall, at the beginning of the diagram, trees take energy(sunlight+ carbon dioxide) to grow. However, it has a long process to form ethanol to make it able in performing in various purposes.
After plants and trees grows fully, it is taken by farmer in tractor to harvest in machine. All full grown trees are putted in machine to pre-process and it form small pebbles like structure. Cellulose is made after pre-processing and it is taken in lab to form different chemicals.
As the processing to form various chemicals is ready, sugar particles is formed and microbes are added to fulfill the complete requirement. Succeeding all the process, ethanol is finally produced and it can be used in various transportation vehicles. Biofuel is important to run the machine. After being used by vehicle, it form carbon dioxide and again all the life cycle process of biofuel production is started from the beginning.
