As of 2011, approximately 45% of US corn production is being used for ethanol production.
Assuming the dry-milling method of ethanol production (the most common), one 56-pound bushel of corn makes 2.7 gallons of fuel ethanol and 17.4 pounds of dried distillers' grain. This means that 69% of the corn went into the ethanol.
Because we use it for everything including the growing of corn used to make ethanol.
The nation of Russia produces about 6 to 7 million tons of corn per year. The production of that grain has been going up consistently for several years.
Corn is one of the major crops grown in the United States. US production is many times that of any other nation. On average, about 80 million acres of corn are raised every year in the US.
Climate is the primary reason. Much of Canada is north of the primary temperate corn-producing area. Wheat is more cold-tolerant than corn and has a shorter growing season as well. Corn production in Canada tends to be limited to short-season varieties which typically don't yield as much.
Nevada is not one of the powerhouses of corn production. They do other things much better. For corn, they convert other state's grains into ethanol. Most of their corn crop goes to silage -- 130,000 tons.
Currently a bushel of corn produces about 2.8 gallons of ethanol. With better varieties that figure will increase to 3 gallons. In the near future, the corn distillate will be processed again, yielding some more ethanol.

If you mean breakfast cereal, less than 1% of the US corn crop is used for this purpose.
Not at all. Ethanol is produced from field corn. Corn for human food is sweet corn. They are completely different, and neither has any effect on the other. Food costs are much more greatly affected by transportation costs than anything else.
Corn is a subsidized crop in the US. This makes corn a very cheap crop for farmers to produce, that is why there is so much of it (see its use as a sweetner -HFCS, and Ethanol). Tax subsidies are granted to farmers from tax dollars that US citizens pay, so the answer to your question may be both taxed and subsidized but the more relevant answer is that corn is a subsidized crop.
Much of it is used for feeding livestock and a large amount is used in the production of ethanol. However, an amazing 44% of Illinois corn is exported (IL Dept of Ag). That is probably the majority single use for the state.
Ethanol comes from corn, we all know that. But the problem created by using ethanol as a biofuel is that it puts a greater demand on corn stocks which can and will go to the point where demand is much higher than supply. Corn is also grown as a foodstuff for humans and a feedstuff for livestock. So when you get a demand for ethanol AND a demand for corn as a food and feed, problems like availability for ethanol production become very difficult and more of an ethical and food issue than anything. Only so much corn can be grown every year and corn can be grown only in certain areas, so using ethanol as a biofuel alone is an inconceivable feat in itself. Other biofuels or alternative energy sources for vehicles must be conceived in order for corn to be freed up for use as food.
Growing corn can be bad for the soil (APEX)
It varies from year to year, of course, but US production averages about 13 billion bushels per year.
roughly 20 percent
In 2001 the U.S. corn crop was estimated at 9.5 billion bushels.
