Image for topic: Essay: Biofuel Production / Ethanol : how ethanol is made

Our system will evaluate the answer based on this AI-generated description.

The image illustrates the biofuel production process for ethanol, beginning with energy (sunlight + carbon dioxide) enabling plant and tree growth, followed by harvesting; it then shows carbon dioxide release during pre-processing, with cellulose moving to processing; sugars are formed, and microbes are added; ethanol is produced, with carbon dioxide emitted by vehicles, transport, and aircraft utilizing ethanol.

Given the complexity of the image, the above description may not be entirely accurate.

The graph illustrates the processes how ethanol which is a biofuel is produced through various steps.

Overall, the production consists of ten steps where the main processes include harvesting of plants, processing of cellulose and the recycling of carbon dioxide emitted by transports to make more ethanol.

The cycle begins with plants and trees synthesising energy with sunlight and carbon dioxide which is a waste product. Then, the greens are harvested to be pre-processed into a cellulose by a specific machinery.

Followed by the production of cellulose, it is processed to be synthesised into sugars. The sugars are then combined with microbes to produce the end product, ethanol. Lastly, the ethanol made is used by various machines, including small vehicles, large transport cars and airplanes. These form of transportations give off carbon dioxide which is then used up by the plants to start the cycle again.

Task Response

The report adequately covers the main stages of ethanol production, presenting a clear overview of the process. To improve, consider adding more specific details about each stage and ensuring precise language throughout. For example, elaborating on the type of machinery used in pre-processing or the specific microbes used in ethanol production could enhance the report. Also, ensure that the description of the cycle's beginning and end is clearly linked to the diagram's representation of carbon dioxide recycling. The report falls short of the required 150 words.

Coherence & Cohesion

The report presents a generally clear overview of the ethanol production process. However, the introduction could be more concise, and the overall structure could benefit from clearer transitions between steps. Consider using more varied cohesive devices to improve the flow and connection between sentences and paragraphs. For example, using transition words like 'Subsequently,' 'Furthermore,' or 'In addition' can enhance the logical progression of ideas.

Lexical Resource

The vocabulary used is adequate for describing the process, but there's room for improvement by incorporating more specific and technical terms related to biofuel production. For instance, instead of 'greens,' you could use 'biomass' or 'plant matter.' Varying your word choice can make the description more precise and engaging. Also, ensure that the terms are used accurately in context.

Grammatical Range & Accuracy

The report contains several grammatical errors and phrasing issues that affect clarity. For example, 'The graph illustrates the processes how ethanol which is a biofuel is produced through various steps' is awkward and can be simplified to 'The diagram illustrates the process of ethanol production.' Pay close attention to sentence structure, subject-verb agreement, and correct use of articles. Proofreading carefully for these errors will improve the overall quality of your writing.
