The element commonly referred to as the "building block of life" is:
Carbon
Carbon is tetravalent and shows catenation — it can bond with itself and with H, O, N, etc. to form long chains, branches and rings.
This allows a huge variety of organic molecules — carbohydrates, proteins, lipids and nucleic acids — that make up living things.
Iron and sulphur are needed only in small amounts, and helium is an inert gas.
Hence, carbon is called the building block of life.
