Trees growing from the air

Most people are very deluded about trees thinking that trees are getting all nutrition from the ground. But if you remember, wood consists mostly of carbon (~ 49%), oxygen (~ 44%) and hydrogen (~ 6%) and only for 0.3-1.8% of minerals. You can always see theese minerals when your campfire is burn to ashes. Ash contains compounds of phosphor, calcium, kalium, magnium and some other elements.

So, where do the trees are getting the carbon? From the air! Trees are absorbing CO₂ from the air water from the ground and growing up. But is the water really comes from the ground? Usual answer is no. Water comes from the clouds with the rain. Look at the tree's roots they growing not too deep but widely near the ground surface to get all the moisture from the rain. There is some tropic orchids that grows on the trees and absorbs moisture directly from the air.

It is the up side down world isn't it?
