Explanation:
Detailed explanation-1: -Ethanol is a domestically produced alternative fuel most commonly made from corn. It is also made from cellulosic feedstocks, such as crop residues and wood-though this is not as common. U.S. ethanol plants are concentrated in the Midwest because of the proximity to corn production.
Detailed explanation-2: -biofuel, any fuel that is derived from biomass-that is, plant or algae material or animal waste. Since such feedstock material can be replenished readily, biofuel is considered to be a source of renewable energy, unlike fossil fuels such as petroleum, coal, and natural gas.
