The graph shows the full process of ethanol, a biofuel and alchol, being manufactured from plants and trees and a few ways of which it gets consumed in. The graph visually demonstartes this procress by using a demonstrative images alongside small text boxes which list off the name of whatever drawing is next to it
Ethanol starts off as Plants and trees which matures using energy, sunlight and carbon dioxide and ends off as a source of fuel for vechiles such as transportation trucks and cars, however another way that ethanol can be used is by marine animals for fuel. What is common between each type of consumer is that these transferers of ethanol rearange it into carbon dioxide which is realesed into the air as a pollutant.
looking deeply into the graph, we can see this process up close of which ethanol is made up from plants and trees after they use co-existing carbon dioxide in the air into fuel sources to grow. Pre growing, the trees are harvested by lumberjacks and Man-made harvesting tools, such as trucks which is used to transfer the trees into pre-proceesing machines which cut up the wood into mini sized clumbs, these clumbs are later processed into types of sugars which gets combined with molecules that turn them into ethanol as we know it. This alchol is then recycled into carbon dioxide by fuel consumers which repeats the cycle all over again.
This process is then repeated infinitely to make a full cycle of production and lowering production causes due to biological factures and nature which with the help of humans, this process is seemingly flawless.
