Detailed explanation-1: -The four most common elements are oxygen, carbon, hydrogen and nitrogen. Along with calcium and phosphorus, they make up 99% of the mass of living organisms.
Detailed explanation-2: -A lot of chemical elements are necessary for the healthy life of any living organism. The elements that are present in the highest quantities in living organisms are oxygen, carbon, hydrogen, nitrogen, sulfur, and phosphorus. These elements make up about 99% of their living mass.
Detailed explanation-3: -Living organisms, however, are made of only a small selection of these elements, four of which-carbon (C), hydrogen (H), nitrogen (N), and oxygen (O)-make up 96.5% of an organism’s weight.
Detailed explanation-4: -Most common elements in living things are carbon, hydrogen, nitrogen, and oxygen. These four elements constitute about 95% of your body weight.
Detailed explanation-5: -The human body is approximately 99% comprised of just six elements: Oxygen, hydrogen, nitrogen, carbon, calcium, and phosphorus. Another five elements make up about 0.85% of the remaining mass: sulfur, potassium, sodium, chlorine, and magnesium.
