*In the human body, 6 elements that make 99% of it (all % by mass) are:

Oxygen- 65%

Carbon- 18%

Nitrogen- 10%

Hydrogen- 3%

Calcium- 2%

Phosphorus- 1%

Answer 2

Carbon is a huge part of living organisms as it is in all organic compounds, such as fats and proteins.

Hydrogen is also a part of fats and proteins, as well as an element in water, which makes up a large percentage of the bodies of living organisms.

Oxygen too is in water, fats, and proteins.

Nitrogen is a big part of amino acids, which make up proteins and DNA.

Phosphorus is a part of the phospholipid bilayer, also called the cell membrane, which surrounds every cell in the body.

Sulfur is found in 4 amino acids, making it important in protein synthesis, and it also plays a role in cellular respiration, a crucial process for each of the organism's cells.

Thus, the six most abundant elements are carbon, hydrogen, oxygen, nitrogen, phosphorus and sulfur (C,H,O,N,P,S).

Answer 3

The six most abundant elements in living organisms are carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur. These elements are essential for building biological macromolecules such as proteins, carbohydrates, lipids, and nucleic acids that form the basis of life.
