1. Ethanol is a biofuel made from what agricultural commodity? 2. What is the term used to describe the production of aquatic animals and plants under controlled conditions?

1.)

Ethanol and biodiesel are the primary renewable fuels produced in the U.S. today. Fuel-grade ethanol is produced by fermenting starch and sugars in plant materials to yield a colorless, clear liquid that is sometimes called grain alcohol, ethyl alcohol, or EtOH. It has the same chemical properties regardless of whether it is made from grain, sugar cane or beets, or cellulosic grasses and wood fibers. Fuel-grade ethanol contains a small amount of denaturant, such as gasoline added before it is sold as motor fuel, and does not affect its performance, but distinguishes it from beverage or pharmaceutical alcohol.

Within the last ten years, US fuel ethanol production has grown to be the major player in renewable fuels supply. Besides reducing US dependence on foreign oil, it provides a motor fuel with significantly lower emissions that will meet standards set by the Environmental Protection Agency under the Clean Air Act. In rural America, the boom in ethanol production has become a driver of economic development by adding significant value to bulk agricultural commodities, such as corn and sugar beets

2.)Aquaculture (less commonly spelled aquiculture[2]), also known as aquafarming, is the farming of fish, crustaceans, mollusks, aquatic plants, algae, and other organism.
