Combustion of fossil fuels (coal, oil and natural gas).
The natural carbon cycle of the earth.
Two natural processes that release carbon into the atmosphere are volcanic eruptions and wildfires. However, there are others and some of them include burning fossil fuels and transport.
Respiration and Combustion.
Volcanos release sulfur dioxide, carbon dioxide, and ash to the atmosphere at the same time
RespirationCombustionDecayWeatheringThe major human processes that release carbon dioxide are the burning of carbon fuels (wood, coal, oil, gas) and the cellular respiration of animals and plants. CO2 is also released by the weathering of carbonate rocks, especially by acid rain.Cellular respiration is mainly balanced by the removal of carbon by photosynthesis, which releases oxygen. This is essentially the reverse process, removing the energy stored by forming carbohydrates.In terms of what process releases the most carbon dioxide into our atmosphere it is decaying organic matter. Total natural decay accounts for over 80% of all CO2 released annually. Natural processes in total account for 93% of all CO2 releases.

Growing vegetation, like trees, plants and crops, removes carbon dioxide from the atmosphere. The other natural method is the carbon cycle, which moves carbon in and out of the atmosphere, in and out of the oceans, and in and out of the land.
the death of plants and animals release nitrogen and carbon dioxide gases
Carbon moves through the carbon cycle in all processes, except for the burning of fossil fuels. Fossil fuel burning releases carbon dioxide (CO2) into the atmosphere, which disrupts the natural carbon cycle by increasing the concentration of CO2, a greenhouse gas, in the atmosphere.

Several processes release carbon as gases (carbon dioxide, carbon monoxide, methane) into the atmosphere. Three important processes are fuel combustion, respiration, and methane release. -- Combustion of carbon-based fuels (wood, alcohol, biogas, or fossil fuels) remove oxygen and combine it to form carbon dioxide and other compounds. -- Plant and animal respiration release carbon dioxide. This is the reverse operation of photosynthesis. -- Methane is released from ruminant animals, from decomposition of organisms, and from ocean-bottom clathrate deposits.
The two main processes that put carbon back into the atmosphere are the respiration of living organisms, including plants and animals, and the combustion of fossil fuels. Respiration releases carbon dioxide as a byproduct, while the burning of fossil fuels, such as coal, oil, and natural gas, releases carbon dioxide that has been stored underground for millions of years. Both processes contribute to the accumulation of carbon dioxide in the atmosphere, leading to climate change.

One natural process that adds carbon dioxide to the air is the process of respiration by plants, animals, and microorganisms. During respiration, these organisms release carbon dioxide as a byproduct. Additionally, volcanic eruptions also contribute to the release of carbon dioxide into the atmosphere.
The carbon cycle is a natural biogeochemical cycle whereby carbon as CO2 is transferred from the atmosphere to the land and ocean, where it resides in another form before returning to the atmosphere as CO2. The principal processes involved in transfer from the atmosphere are the dissolution of CO2 in the oceans and the uptake of CO2 by the photosynthesis of green plants. The processes involved in return to the atmosphere are the release of CO2 from the ocean in regions in which the surface of the ocean has become saturated with CO2 and the oxidation of organic matter by respiration or fire, which essentially reverses the photosynthetic process: 6CO2 + 12H2O ⇔ C6H12O6 + 6O2 + 6H2O
The burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, which releases carbon dioxide (CO2).
The two main biological processes in the carbon cycle are photosynthesis (which absorbs carbon) and cellular respiration (which moves it back to the atmosphere as carbon dioxide).
