What makes the carbon atom so important in biology? It is a common element on Earth. It bonds to only a few other elements. It can form a variety of carbon skeletons and contain functional groups. It has very little electronegativity, making it a good electron donor.

It can form a variety of carbon skeletons and contain functional groups

Explanation:

Carbon atom is important in biology because it can form a variety of carbon skeletons and contain functional groups. These enable carbon to be able to bond with itself and a variety of other elements. Thus, carbon is able to be the major component of important biomolecules of life such as deoxyribonucleic acid, carbohydrate, proteins, and lipids.
