Question

Quizplus · Accepted Answer

Phosphorus occurs in the lowest concentration in global living matter compared to the other elements listed. While elements like carbon, hydrogen, and nitrogen are fundamental components of organic molecules (e.g., proteins, nucleic acids, carbohydrates, and lipids), phosphorus, though essential for life (e.g., ATP, DNA, RNA), is present in significantly lower concentrations. Calcium, while less abundant than carbon, hydrogen, and nitrogen, is more concentrated than phosphorus in living organisms, primarily due to its role in structural components such as bones and teeth in animals and cell wall stability in plants.
