The diagram below shows how a biofule called ethanol is produced. Summarize the information by selecting and reporting the main features and make comparison where relevant.

The chart provides information about the process by which ethanol is produced from biofuel, highlighting the key phases from the initial inputs to the final outputs.

Overall

Linking Words

, there are three different pathways;

for instance

Linking Words

, carbon dioxide emissions can be generated by cars,

whereas

these emissions are

also

produced by planes.

However

Linking Words

, the nature of each process varies significantly. As the chart illustrates, after the growth of trees and herbs

due to

the energy from the sun, they are harvested by trucks.

Then

Linking Words

, they enter the pre-processing step to obtain cellulose, which can

also

Linking Words

be processed to provide sugars. After that, these sugars are mixed with microbes to get ethanol, which is used as an energy source for cars, trucks, and planes.

Furthermore

Linking Words

, after the consumption of the biofuel by these transportation means, they generate carbon dioxide emissions in the gas state.

Finally

Linking Words

, the CO2 is distributed in the air, and the plants and trees can be consumed again and again.
