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 by which

ethanol

, a type of biofuel, is produced from

plants

and trees.

Overall

, there are eight main stages in

this

process, starting with the growth of

plants

and ending with the emission of

carbon

dioxide when

ethanol

is used as fuel.

Firstly

,

plants

and trees absorb sunlight and

carbon

dioxide through photosynthesis to grow. Once they have fully matured, they are harvested by farmers and delivered to the pre-processing stages, where the harvested

plants

are cut into smaller pieces or ground to extract cellulose, the main resource for

ethanol

processing. In the

ethanol

factory, enzymes are added to convert the cellulose into sugars. These sugars are

then

fermented by microbes to produce

ethanol

. The

ethanol

is

subsequently

purified to ensure high quality.

Finally

,

this

purified biofuel is distributed via gasoline stations for various vehicles, including trucks, cars, and planes. The

carbon

dioxide emitted from these means of transportation

then

returns to the atmosphere and is reabsorbed by

plants

, continuing the

carbon

cycle.
