The image illustrates the ethanol production process in a cyclical diagram. Starting with sunlight energy, the process involves growing plants and storing water. Harvesting comes next, followed by pre-processing which includes crushing and enzymatic breakdown. The raw materials then undergo fermentation to produce ethanol. Post-fermentation steps include distillation to concentrate the ethanol. The diagram further indicates energy transfer to vehicles after processing. Carbon dioxide is released during combustion and refuels the initial cycle via photosynthesis, closing the loop with energy from sunlight.
Given the complexity of the image, the above description may not be entirely accurate.

The given illustration presents the production method of ethanol. Overall, it is obvious that this cyclic process involves several stages. Also, ethanol is known as a biofuel, because it is produced by natural components and microbes activities.
At first stage, trees and plants adsorb the energy of sunlight and carbon dioxide to grow. Then, in the next step, they are harvested in order to use as raw materials for production of ethanol. During pre-processing, cellulose is made out of trees and plants.
After that, some chemical processes are done on cellulose and turn it into sugars. In the last stage of production, microbes are added to sugars, and ethanol is produced as a consequence of microbes’ activities. Cars, trucks and airplanes use ethanol as a fuel, and emit CO2. The carbon dioxide emissions are used by trees and the whole process is repeated again.
