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 process diagram describes the production of biofuel called ethanol.
Overall, ethanol production includes eight steps, starting from the flora absorbing sunlight and carbon dioxide from the environment, and ending by releasing the carbon dioxide into the air through different vehicles to complete the cyclic formation of ethanol.
Firstly, the plants take energy from the air to grow, eventually becoming tall trees that are ready for harvesting, then some parts of tree are harvested. The harvested part of the plant is now ready for pre-processing, where cellulose is formed and taken to the lab for processing, in which it is converted into sugars.
Next, microbes are added to the sugar in order to make ethanol that is used as a fuel for various types of vehicles such as, cars, buses, bikes, etc. As these vehicles operate, they emit carbon dioxide into the atmosphere, which is then reabsorbed by plants to facilitate their growth. In this way, the cycle continues.
