If you mean which isotope, then carbon-12 is the most abundant. If you mean where does the carbon come from, then it's atmospheric carbon dioxide for plants, and food for animals.
Graphite is the most thermodynamically stable (more than diamond).
The main abiotic reservoir of carbon available to plants is the atmosphere, where carbon exists primarily in the form of carbon dioxide (CO2). Plants absorb CO2 during photosynthesis, using it to produce organic compounds. Additionally, carbon is stored in soils and bodies of water, but the atmospheric CO2 is the most directly accessible source for plants.
No. Carbon has four valence electrons and can make four bonds.
A majority of the earths carbon is located in the ocean.
Carbon is the basis of most molecules that make up living things. Carbon has the unique ability to form long chains and complex structures, making it essential for building macromolecules like carbohydrates, lipids, proteins, and nucleic acids. Additionally, carbon can form strong bonds with other elements, contributing to the diversity and stability of biological molecules.
Most of the Earth's carbon is located in the atmosphere. It is in the form of carbon dioxide
Carbon can form long chains and branched structures, allowing for diverse organic compounds. Additionally, carbon has the ability to form multiple bonds with other elements, leading to a wide range of chemical reactions and compounds. This versatility is what sets carbon apart from most other elements.

In the atmosphere, in the form of carbon dioxide
Carbon, hydrogen, nitrogen and oxygen (in no particular order).
Carbon is considered the most versatile element in living organisms because of its ability to form strong covalent bonds with other carbon atoms and a variety of other elements. This allows carbon to form complex molecules with diverse structures and functions, making it essential for the diversity of life on Earth.
Most of the carbon in the atmosphere is in the form of carbon dioxide, (CO2) gas.
The thing about carbon is that it can form all kinds of carbon-carbon chains; this allows lots of interesting compounds, especially proteins, and a solution of proteins in water is fundamental to all life (as we know it).

The bonds that carbon form are the most important charicteristic.
While most carbon compounds are completely safe and in many cases necesarry for life as we know it, there are some carbon compounds or carbon molecules that are carcinogenic (cancer causing), and others that can form into highly toxic chemicals (cyanide is one of these).
