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.

What is the role of volcanic eruption in nitrogen fixation?
they put carbon dioxide back in the atmosphere
Why does the combustion of biomass release no net carbon into the atmosphere?
Biomass is vegetable matter, like unwanted parts of sugar cane (bagasse), as well as residue from tree felling and other things. When vegetation grows, it removes carbon dioxide (CO2) from the atmosphere. When the same material is burnt as biomass, that same CO2 is put back into the carbon cycle.
How does carbon dioxide get put back into the air?
Carbon dioxide gets put back in the air in a variety of ways. It can come from the burning of fossil fuels, automobiles, industry, the respiration from plants, and the decay of animal matter.
Why is the atmosphere warming?
The atmosphere is warming because the extra carbon dioxide (CO2) in the greenhouse gases of the atmosphere is holding in more of the sun's heat. There is extra CO2 in the atmosphere because by burning coal, oil and natural gas (fossil fuel) we have released CO2 that had been safely concealed underground for millions of years. This has put pressure on the carbon cycle which has not been able to remove it.
Is the Carbon dioxide changing by the same amount each year?
The current level of CO2 in our atmosphere is 390 parts per million. We are now releasing CO2 at astonishing rates into our atmosphere, so to answer your question no. More Carbon Dioxide is being put into our atmosphere each year. There is an average, but that has gone up in the past few decades.
What processes put carbon is found in most of earths atmosphere?
because i don't now by meni

Carbon is removed from the atmosphere and put into food through?

Wow many tons of carbon do you put into the atmosphere annually?
I have no clue. How much do you put in the atmosphere annually?
What is the major driving force of the oxygen cycle?
the main two processes are plant photosynthesis, which takes carbon dioxide out of the air, and plant and animal respiration which put carbon dioxide back into the air.
How do living organisms return carbon to the atmosphere?
They can in many ways including: - just breathing(CO2 into the atmosphere) - decomposing after they have died - burning fossil fuels livestock like cows can also put carbon back into the atmosphere as they excrete methane gas.
What is the advantage of using wind turbines rather than burning fossil fuel to produce electricity?
When energy is created from wind turbines the energy is created from the atmospheres wind currents and no chemical processes are required. With no chemical processes(burning) involved the atmospheres chemical composition is not altered. Burning fossil fuel, simply put is the chemical process of changing a form of concentrated carbon into heat and carbon dioxide. Ancient life on the planet absorbed the carbon dioxide from the atmosphere and time and natural processes sequestered the carbon from the ancient life into coal and oil reserves. When you burn the fossil fuel you are placing the carbon, that was once sequestered through the millions of years Earth has had life, back into the atmosphere thus changing the composition of the atmosphere. The results of putting the carbon back into the atmosphere is debated. Example A: A pin-wheel is attached to a generator. The wind blows the pin wheels blades and the generator makes electricity. This electricity runs into a coil and the energy is transferred into heat and you warm your hands up. Example B: You have a dead stick from a tree in your yard that grew for a year and fell off the tree. During that year the tree converted energy from the sun and the carbon from the air to create the stick. You burn the stick and warm your hand.
How is a cow eating grass part of the carbon cycle?
The cow eats the grass; as the grass regrows, it takes carbon dioxide from the atmosphere into its growing leaves and roots (along with other nutrients) and stores the carbon molecules in the soil. The cow that ate the grass also has to excrete her wastes, which turns back into the soil through the act of decomposition. She also releases carbon into the atmosphere, but it is quickly put back into the earth by the plants that breathe it in and exhale oxygen through the act of photosynthesis.
Why does the combustion of biomass release no net carbon into the atmosphere?
Biomass is vegetable matter, like unwanted parts of sugar cane (bagasse), as well as residue from tree felling and other things. When vegetation grows, it removes carbon dioxide (CO2) from the atmosphere. When the same material is burnt as biomass, that same CO2 is put back into the carbon cycle.
How does get put back into the air?
Oxygen is a "waste" byproduct of photosynthesis. Plants use sunlight to combine water and carbon dioxide into sugar and "excess" oxygen molecules, which is then released into the atmosphere (or ocean, in the case of algae).
How does an ice age lead to global temperatures rising?
An ice age will put more carbon into the atmosphere. The increase in carbon captures the Sun's energy and the planet begins to warm.
