Answer:
The living organism contain more hydrogen atoms than other atoms because it is bounded with oxygen to form H2O and Oxygen has 16 times the mass than the hydrogen.
Explanation:
As we know oxygen is the most abundant molecule in human body (65%). Human body has approximately 60% of water which is composed by hydrogen and Oxygen. Other than that most of the important biological molecules like fats, carbohydrates and DNA contain hydrogen as crucial part of the structure. So hydrogen atoms are found more abundantly than other molecules.
