Explain why living organisms contain more hydrogen atoms than any other atoms

Explanation:

Much like carbon, hydrogen is ubiquitous to molecules that form the basic components of life. Indeed, hydrogen is essential because it easily bonds with carbon. This is because hydrogen effectively serves as a linking element between the carbon base of a chain and other elements; hydrogen's high level of electronegativity is what allows it to play this role. Frequently hydrogen will end up linking carbon to more hydrogen atoms, and this continuing chain of hydrogen atoms is what creates the level of complexity needed to create an organic molecule (e.g., a fat or protein).
