hydrogen
Carbon is the most important element to living things because it can form many different kinds of bonds and form essential compounds.
Water; all living things require some water.
Water makes up about 65% of the human body.
Carbon is the element most associated with living things and is found in all four macromolecule types (carbohydrates, lipids, proteins, and nucleic acids). Carbon's versatility in forming covalent bonds allows for the vast diversity of organic compounds found in living organisms.
oxygen
The element that is most abundant in living things is carbon. The other five elements that are most abundant in living things are hydrogen, nitrogen, oxygen, phosphorus and sulfur.
Oxygen is the most important factor for living things.
