If one single corn stalk absorb 40 gallons of water per day how much does a 60-80 'tree absorb daily?

That would depend on the tree. Some trees need more water than other types do. You can't simply extrapolate from the amount water used by corn to determine the amount of water a tree will use.

Wait, A gallon of water is aprox 8lbs, that would mean that a single corn stalk absorbs 320lbs of water a day yet still weighs only 5lbs at any one time. am I missing something?

I thought that was a little off. An acre of corn grows about 28,000 stalks at 40 gallons of water a day that would equal 1,120,000 gallons of water per acre per day. corn only evaporates at 4000 gallons of vapor per acer per day. Americas lower 48 receives about 4 cubic miles (1.1 trillion gallons)of water in rain per day. As of 2005 America grows 81 million acres of corn. The math gives you a number of 89,100,000,000,000,000,000 gallons of water per day. Does anyone even know what that number is? That much fresh water doesn't exist. Most fresh water is found in the form of ice, at 7,000,000 cubic miles. The second largest source is ground water at 2,000,000 cubic miles. surface fresh water, lakes, rivers, inland seas only have 60,000 cubic miles. thats why I was so skeptical with my comments. I went to about 20 web sights to do this so don,t ask for links, just google it. thats what i did. and if your curious, there is 326 million cubic miles of ocean that would be 326,000,000,000,000,000,000 gallons of water. Give or take.
