Band 5+: The diagra below shows how a biofuel called ethanol is produced Summarise the information by selecting and repoting the main features and make comparisions where relevant.

The diagram provides information on the production of ethanol.

Overall, there are ten steps which start from energy from the sun and carbon dioxide from the atmosphere and ending with vehicles buring fules back into gas.

Firstly, sunlight and carbon dioxidde is being converted to power by plants and tress through photosynthesis in order to grow. THose tree are then harvest via machinary, and pre-process into cellulose. Next, the main process of tranforming cellulose into sugars by varoius chemicals.

Seventhly, the trated sugars are then feed to microbes. These organism digest the glucose as food and execret out biofuel which is called ethanol. Lastly, the fuels is then used for transporation like cars, planes, and trucks. Those same vehicles then produce greenhouse emmission which will continue the loop
