The diagram below shows how a biofuel called ethanol is produced.  Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The diagram illustrates the process of manufacturing

ethanol

, commonly known as biofuel, highlighting different stages - including harvesting, pre-processing, and utilizing - and the repetitive cycle.

Overall

, producing

ethanol

involves three primary stages: harvesting and pre-processing plants, chemically converting them into

ethanol

, and utilizing it as fuel for transportation.

This

process is

then

repeated.

According to

the data, energy, encompassing sunlight and CO2, contributes to the growth of plants and trees. These materials are harvested once they mature and

then

transported to the pre-processing machine, broken down into small pieces of cellulose. In the second stage, the cellulose is sent to an experiment facility, which conducts chemical processing to convert it into sugars. Microbes are

subsequently

added to the sugars, initiating fermentation, which generates

ethanol

.

Finally

,

ethanol

is used as a primary fuel for various vehicles,

such

as planes, trucks, and cars. During combustion, CO2 is released back into the atmosphere, serving as the nutrient for plant growth and continuing the cycle.
