Bio-molecules
complex carbon compounds produced in living things e.g. proteins, carbohydrates, fats and oils, DNA
Anthopogenic CO2
carbon dioxide generated by human activity
Biosphere
the sum total of all living matter on Earth
Carbon sequestration
The capture of carbon dioxide from the atmosphere or capturing anthropogenic CO2 from large scale stationary sources such as power stations before it is released into the atmosphere
Carbon sink
A store of carbon that absorbs more carbon than it releases
Greenhouse Gas
Any gaseous compound in the atmosphere that is capable of absorbing infrared radiation, thereby trapping and holding heat in the atmosphere
Weathering
The breakdown of rocks insitu by a combination of weather, plants and animals. Releases Carbon into the atmosphere
Inorganic carbon

Organic carbon
Carbon that is found in living matter such as palnts and animals
