The diagram shows how biofuel called ethanol produced

The process below illustrates how a biofuel called ethanol is manufactured.
In general, it requires 8 stages to produce ethanol. We can see that ethanol is made using 2 main energy sources, sunlight and carbon dioxide. In addition, vehicles produce CO2, and it proceeds.
At the firts stage in the production of ethanol, energy, (sunlight and carbon dioxide) is required to growth of the plants and trees. Then, these natural goods are harvested with tractors, and these timbers bring to the pre-processing. After that, they cellulosed, as well as passes through processing, and added some chemicals.
Then, that processed celluloses are converted to sugar. Finally, microbes and germs are added to the sugar to create ethanol. Next, this biofuel, used as a petrol for different types of vehicles, including trucks, cars, and planes also. After that, these vehicles produce carbon dioxide, eventually this carbon dioxide become an energy source for plants as well as trees, and this process continues.

5.0

The essay follows a logical sequence but lacks clear transitions and some clarity in the explanation of stages.

Suggestions
  • Use linking words to enhance flow.
  • Clarify the cycle of energy sources and their role.
  • Ensure each stage is distinctly explained.

The vocabulary is basic and lacks variety. Some terms are used incorrectly.

The essay contains grammatical errors that affect clarity and comprehension.

The essay describes the process but lacks detailed explanations of each stage and energy cycle.

Suggestions
  • Provide more detailed descriptions of each stage.
  • Clarify the role of carbon dioxide in the process.
  • Ensure all stages are covered thoroughly.
