Nature produces the vast bulk of carbon dioxide in the atmosphere. Rotting trees, and dead matter produce over 90% of the current levels of carbon dioxide.
Man produces between 3 and 6 percent of all CO2 annually.

∙ 12y agoThe atmospheric source of carbon that is part of the carbon cycle is carbon dioxide. Carbon dioxide moves into the atmosphere from the oceans, the land, rocks and soil, from vegetation and from animals. However, not all of the carbon dioxide in the atmosphere is natural. Humans are adding carbon dioxide to the atmosphere by burning fossil fuels.

What is the role of CO2 in the atmosphere?
It used in carbon cycle.
What role does the carbon cycle play in this problem of global climate change?
In the desert, the carbon cycle is a continuous and non-stop process. Plants and the atmosphere exchange carbon. Carbon is released when plants breathe and when organisms die. The cycle starts again when plants use the carbon that has been released.
How is carbon dioxide fixed in the atmosphere?
It is not fixed in the atmosphere. It moves as part of the carbon cycle in and out of the oceans, the atmosphere and the land.
Dose bacteria play a particularly important role in the water cycle?
The nitrogen cycle - /> cycling nutrients, causing diseases, flavoring foods, producing medicines As far as I know, they play an important role in the carbon cycle. When a living thing dies, bacteria attack the body thus releasing all the elements such as carbon back into the atmosphere.
What do water cycle and carbon cycle have in common?
they both go through the entire atmosphere
What is the role of CO2 in the atmosphere?
It used in carbon cycle.
What role does the combustion of fossil fuels have in the carbon cycle?
It increases the carbon dioxide in the oceans. It adds carbon dioxide to the atmosphere.
What role does the carbon cycle play in this problem of global climate change?
In the desert, the carbon cycle is a continuous and non-stop process. Plants and the atmosphere exchange carbon. Carbon is released when plants breathe and when organisms die. The cycle starts again when plants use the carbon that has been released.
What is the carbon cycle?
The carbon cycle is a process by which carbon is cycled between the atmosphere, land, water and organisms. Carbon enters a short-term cycle in an ecosystem when producers, such as plants, convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis.The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth
Do volcanic activity and burning fossils fuel play a role in the carbon cycle?
Yes, both add CO2 to our atmosphere
Does carbon cycle involved an exchange of carbon between the atmosphere and geosphere only?
No, as well as the geosphere, the carbon cycle also moves carbon between the atmosphere, the biosphere, and the hydrosphere.
What cycle does the atmosphere not play a role in?
In nitrogen cycle
Process by which carbon circulatesaroundthe earth as plants remove carbon from the atmosphere and animals add carbon to the atmosphere?
Carbon Cycle.
How is carbon dioxide fixed in the atmosphere?
It is not fixed in the atmosphere. It moves as part of the carbon cycle in and out of the oceans, the atmosphere and the land.
