The image illustrates the biofuel ethanol production process, starting with plants and trees absorbing energy (sunlight + carbon dioxide), followed by harvesting. The harvested material undergoes pre-processing. Cellulose is extracted, moved to the processing phase transforming it into sugars then microbes are added converting sugars into ethanol, which is then stored. The process releases carbon dioxide throughout several stages including harvesting, pre-processing, and the final ethanol production stages. The cycle iteratively emphasizes energy absorption and carbon dioxide emissions across various transformational stages from plants to ethanol.
Given the complexity of the image, the above description may not be entirely accurate.

The diagram illustrates the process of producing ethanol, which is used as a biofuel in transportation.
Overall, carbon dioxide collected from plants and trees serves as an energy source following pre-processing and chemical treatment.
Initially, trees that absorb sunlight and carbon dioxide are harvested by a specialized machine and then proceed to a pre-processing stage. The resulting cellulose then undergoes chemical treatment.
Once the conversion of sugars from cellulose has been done, the addition of microbes to the sugars forms the end product ethanol. Finally, this ethanol is used in vehicles, releasing carbon dioxide into the atmosphere, thus completing a closed cycle.
