Band 6+: The diagram below shows how a biofuel called ethanol is produced. Summarise the information by selection and reporting the main features, and make comparison where relevant.

The diagram below demonstrates the process involved in the biofuel production known as ethanol.

Overall, there are 10 stages involved in the production of ethanol, beginning with growing plants and trees under the natural energy and finishing with ethanol being used in various types of vehicles.

The process of how ethanol is produced start off with trees and plants are grown to absorbing energy resource combining sunlight with carbon dioxide. After that, the full-grown plants and trees going to be harvested by the machine then undergoes a pre-processing to separate cellulose from the trees and plants. Subsequently, the cellulose is going through a processing of converting it into a sugars and microbes are being added to the process to form as an ethanol. Once the ethanol is manufactured, it is going to be utilized as a fuel for engines in transportation such as cars, trucks and planes. Finally, the carbon dioxide which released into the atmosphere from the vehicles going to reused for the growth of plans and trees that complete the cycle for the production of ethanol.
