Oil and gas are hydrocarbons which store carbon. They release large amount of carbon into the atmosphere which is then used by plants and finally animals to make food and eaten as food, thus completing the carbon cycling.
Carbon cycling refers to the process by which carbon is cycle between the living and non-living components of the earth.
In carbon cycling, carbon flows between living things when they use it to build the materials of their bodies and flow out to the earth when these living organism die.
Oil and gas deposits are the remains of animals and planet who died long ago and whose remains were converted deep down in the earth crust by intense heat and pressures.
Oil and gas are hydrocarbons which serve as stores of carbon. When these oil and gas are burnt by man for his energy needs, they release large amount of carbon into the atmosphere which will then be used by plants to make food as well as to build their tissues,
Also, animals eat these plant food, thus completing the carbon cycling.
