Carbon!
Nitrogen is an element it has an atomic number of 7
Carbon is the basic element that serves as the building block of all living organisms. It plays a fundamental role in the structure of biological molecules like carbohydrates, lipids, proteins, and nucleic acids.
Carbon is the element found in all life on Earth. It is a fundamental building block for organic molecules like proteins, lipids, carbohydrates, and nucleic acids that make up living organisms.
Monomers
An atom is a fundamental building block of matter. It consists of a nucleus composed of protons and neutrons, surrounded by electrons in orbit. Atoms combine to form molecules, which make up all substances found in the universe.
The main building block for plastics is not an element but rather a molecule that's called 'monomere' which turns into a 'polymere' by combining many molecules together (polymerisation reaction) in plastics
It has 4 valence electrons, making it an ideal building-block element.
The building block of all molecules is an atom. Atoms combine together through chemical bonds to form molecules.

Nitrogen is an element it has an atomic number of 7
Carbon is present in all living organisms and in many non-living things, such as minerals, rocks, and the atmosphere. It is the fundamental building block of all organic molecules.
Carbon.
because carbon has a tendency to form stable bond with itself more then any element till known.
Carbon is the element that is the building block of all life on Earth. It is essential for the formation of organic molecules that make up living organisms.
Amino acids
An "Atom" is the basic building block of all molecules [first] and [then] biomolecules.
