The given diagram illustrates the process of producing a biofuel named ethanol.Overall, there are seven main steps in the ethanol manufacture, beginning with the phenomenon that plants and trees use biological supplements to grow and ending with vehicles which consume ethanol then release carbon dioxide into the atmosphere.
At the first stage of the diagram, the sunlight and carbon dioxide are absorbed by vegetation to develop what is called photosynthesis. As they are enough to harvest, people collect them by machines then harvested products undergo a pre-processing process that cuts them into stands of cellulose.
Next step, cellulose stands transferred to the laboratory is in processing to manufacture sugars which after that are added with microbes to convert them into ethanol which in turn is used as a fuel to power transports with combustion engines such as planes, trucks or private car,… . These vehicles will burn up the ethanol and release carbon dioxide into the atmosphere. To reiterate this process, emissions continue to circulate in the air and The trees and plants, in turn, consume this as their food, and the cycle restarts.
