Name the component which is found in natural gas as well as biogas.
Natural gas: Natural gas is a mixture of gases that are rich in hydrocarbons. All of these gas (methane, nitrogen, carbon dioxide, and so on) are found in the atmosphere naturally. Natural gas reserves are found near other solid and liquid hydrocarbons such as coal and crude oil, deep inside the earth.
Biogas: Biogas is a mixture of methane and carbon dioxide produced by the bacterial decomposition of organic wastes and used as a fuel.
As a result, methane is found in natural gas as well as in biogas.
