The diagram illustrates the process of producing ethanol, a biofuel. First, carbon dioxide is absorbed by plants, which are then harvested using heavy agricultural machinery. These harvested plants undergo a pre-processing stage, where they are shredded into smaller pieces to prepare them for cellulose extraction.
Next, the cellulose is subjected to chemical reactions, resulting in the production of sugar molecules. Microbes are then added to the processed sugar, initiating a biochemical process that produces ethanol.
Finally, the ethanol is purified and distributed to the market, where it serves as a biofuel for vehicles such as trains, cars, and airplanes. This process efficiently converts plant matter into a renewable energy source, contributing to more sustainable fuel alternatives.
Overall, the diagram outlines the steps involved in transforming plants into ethanol, demonstrating a systematic approach to biofuel production.
