Most Important Organism? Marine plants produce between 70 and 80 percent of the oxygen in the atmosphere.
That is, they absorb carbon dioxide from the air and store the carbon in their roots, trunks, branches and leaves. Fifty percent of a tree by weight is carbon. Thus, if the number of trees is increased, more CO2 will be consumed and the level of carbon dioxide in the atmosphere will reduce.
