Answer: I would say that the most common elements in living organisms are: 1)Oxygen
2)Carbon
3)Hydrogen
4)Nitrogen
Explanation:
1)Oxygen is the most abundant element contained within the living organisms, composing about 65% of the human body. It is also critical for cellular respiration in all aerobic organisms.
2)Carbon is essential for the survival, growth and reproduction of living things. It is a finite resource that comes in different forms and transfers from living to non-living things in various ways.
3)Hydrogen is important because it is involved in the process of enzyme catalysis and because it stabilizes things like nucleic acids and proteins.
4)Nitrogen is an important part of building amino acids and nucleic acids, both which are critical for maintaining life. Amino acids and nucleic acids are essential building blocks for cellular growth and repair in organisms in the form of protein.
