Detailed explanation-1: -Hydrocarbon combustion refers to the chemical reaction where a hydrocarbon reacts with oxygen to create carbon dioxide, water, and heat. Hydrocarbons are molecules consisting of both hydrogen and carbon. They are most famous for being the primary constituent of fossil fuels, namely natural gas, petroleum, and coal.

Detailed explanation-2: -Burning fossil fuels yields carbon dioxide, water and energy; the process of burning fossil fuels is known as “combustion”.

Detailed explanation-3: -When fossil fuels are burned, they release large amounts of carbon dioxide, a greenhouse gas, into the air. Greenhouse gases trap heat in our atmosphere, causing global warming.

Detailed explanation-4: -The burning of fossil fuels is called combustion. Fossil fuel combustion releases carbon dioxide into the atmosphere.

Detailed explanation-5: -To release the energy stored in carbon-containing molecules, such as sugars, autotrophs and heterotrophs break these molecules down in a process called cellular respiration. In this process, the carbons of the molecule are released as carbon dioxide.
