What are the main 4 elements in organisms?
Carbon, hydrogen, oxygen, and nitrogen are the most important elements. Small quantities of other elements are necessary for life. Carbon is the most abundant element in living matter.
What are the 4 elements found in the largest amounts in living organisms?
Living organisms often contain trace amounts of several elements, but the most abundant ones are oxygen, carbon, hydrogen, nitrogen, calcium and phosphorus.

What is not one of the 4 most common elements that are found in living organisms?
Complete Answer: 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. Sulphur is the element that is not one of the four most common elements.
What element is in every living organism?
The four elements common to all living organisms are oxygen (O), carbon (C), hydrogen (H), and nitrogen (N).
What elements make up each of the 4 macromolecules?
There are four classes of macromolecules (polysaccharides or carbohydrates, triglycerides or lipids, polypeptides or proteins, and nucleic acids such as DNA & RNA). Carbohydrates and lipids are made of only carbon, hydrogen, and oxygen (CHO). Proteins are made of carbon, hydrogen, oxygen, and nitrogen (CHON).

Which elements are essential for living organisms to survive?
Water, land, air (oxygen) are the elements which are essential for living organisms to survive.
What are the four major elements of living organisms?
If major also means essential for life, then “trace elements” are very major though they make up just 0.5% of the atoms in an organism. The four most important elements in cells are carbon, hydrogen, oxygen and nitrogen. However, other elements — like sodium, potassium, calcium and phosphorus — are also important.
