The substance that is predominately absorbed in rain forests would be carbon dioxide, I believe. As many tropical trees are present and will uptake CO2 to synthesize glucose or sugar as a product of photosynthesis.
The rain forests receives adequate annual rainfall per year. It can sustain diversity of life forms. Plants grows abundantly in rain forests. It is evident that these forests are the carbon sinks which means trees and plants in the forests absorbs carbon dioxide from the atmosphere for photosynthesis. Hence, reduces the level of carbon dioxide which is potent air pollutant gas.
<span>C6H12O6 + 6O2 ==> 6CO2 + 6H2O </span><span> This chemical reactions proves the fact that the products of photosynthesis are reactants of respiration hope it helps</span>
Equal forces are being applied from opposite sides, so they cancel out. Think about pushing on both sides with the same amount of pressure on both sides. Its not gonna move. Hope I could help!
