Photosynthesis is important in taking carbon from the atmosphere . This is why forest are great carbon sinks because they sequester carbon from the atmosphere. Cellular respiration, on the other hand, is the opposite of photosynthesis. It increases the levels of carbon in the atmosphere by breaking down carbon-based foods to carbon dioxide.
The answer is nitrogen. It comprises
approximately 78% of the atmospheric air.
Nitrogen can be found in most life
processes including as a component of amino acids –amino group (NH3-). It is also involved
in the structure of nucleosides that are critical
in the formation of nucleotides and ATP.
