Carbon is most commonly obtained from coal deposits, although it usually must be processed into a form suitable for commercial use. Three naturally occurring allotropes of carbon are known to exist: amorphous, graphite and diamond.
In this way, what are the four types of carbon?
Living things contain four major types of carbon-based molecules. The organic molecules in living things fall into four major groups— carbohydrates, lipids, proteins, and nucleic acids. You may already be familiar with these types of molecules and their functions. Carbohydrates include sugars and starches.
What are the different forms of carbon takes on earth?
Carbon is found in the non-living part of the hydrosphere, atmosphere, and geosphere as:
- carbonate (CaCO3) rocks: limestone and coral.
- dead organic matter, such as humus in soil.
- fossil fuels from dead organic matter (coal, oil, natural gas)
- carbon dioxide (CO2) in the air.
- carbon dioxide dissolved in water to form HCO. 3−
