What is the source of carbon dioxide in air?

Respiration by animals and plants and the burning of fuel is the source of carbon dioxide in the air.

Extra information: 

The Earth's atmosphere is made up of a mixture of gases called "air." These are colorless and odorless gases. It is made up of 78 % nitrogen, 21% oxygen, and 1 % other gases and water vapor. It also contains trace amounts of carbon dioxide, neon, helium, methane, krypton, hydrogen, nitrous oxide, xenon, ozone, iodine, carbon monoxide, water vapors, and ammonia.

Carbon Dioxide: Carbon dioxide makes up about 0.03 % of the atmosphere naturally, but it is growing as a result of the combustion of fossil fuels. Carbon dioxide is used by plants and eubacteria during photosynthesis.

The natural sources of carbon dioxide include most animals, which exhale carbon dioxide as a waste product. Human activities that lead to carbon dioxide emissions come primarily from energy production, including burning coal, oil, or natural gas.
