The primary source of CO2 in the atmosphere is the burning of fossil fuels such as coal, oil, and natural gas. When these fuels are burned for energy, carbon stored in them is released as CO2 into the atmosphere. Other sources include deforestation and land use changes.
Volcanic activity was the primary source of CO2 in the Earth's early atmosphere. During this time, volcanic eruptions released large amounts of gases, including carbon dioxide, into the atmosphere.
The primary source of Earth's atmosphere is outgassing from volcanic activity and the release of gases from Earth's interior. This process began billions of years ago and continues to contribute to the composition of our atmosphere.
Oceans
The primary source of oxygen in Earth's atmosphere comes from photosynthesis by plants, algae, and some bacteria. During this process, these organisms use sunlight to convert carbon dioxide and water into oxygen and glucose. This oxygen is then released into the atmosphere as a byproduct.
The primary mechanism by which CO2 contributes to global warming is by preventing heat from escaping the atmosphere into space. As more and more heat is trapped in the atmosphere, temperatures increase.

The primary source of carbon for carbon fixation in plants is carbon dioxide (CO2) from the atmosphere. In photosynthesis, plants use the enzyme RuBisCO to fix CO2 into organic molecules, eventually producing glucose for energy.

The primary source of increased CO2 in the atmosphere is the burning of fossil fuels, such as coal, oil, and natural gas, for energy and transportation. Deforestation and land-use changes also contribute by reducing the number of trees that can absorb CO2. Additionally, industrial processes and certain agricultural practices release CO2, further exacerbating the problem. Together, these human activities significantly elevate atmospheric CO2 levels, driving climate change.

Most of the carbon in ecosystems comes from the atmosphere, primarily in the form of carbon dioxide (CO2). Through the process of photosynthesis, plants absorb CO2 and convert it into organic matter, which forms the basis of the food web. Additionally, carbon is also released back into the atmosphere through respiration and decomposition, creating a dynamic carbon cycle. Overall, the atmosphere is the primary source of carbon for the majority of ecosystems.
Oceans
Oceans hold the largest amount of carbon in the biosphere, but this carbon is part of the carbon cycle which moves in and out of the land, atmosphere and oceans.Human activity is the biggest source of additionalcarbon, by our burning of fossil fuels over the past 200 years.
