How does carbon stores affect the amount of CO2 in the atmosphere?
Carbon stores, such as forests, soil, and oceans, act as significant reservoirs that absorb and sequester carbon dioxide (CO2) from the atmosphere. When these carbon stores are disturbed—through deforestation, land-use changes, or ocean degradation—they release stored CO2 back into the atmosphere, increasing greenhouse gas concentrations. Conversely, healthy carbon stores can mitigate climate change by capturing and holding CO2, thereby reducing the overall atmospheric CO2 levels. Maintaining and restoring these carbon sinks is crucial for balancing the carbon cycle and addressing global warming.
Where does the stuff the tree is made of come from?
About half the body weight of a tree is carbon. The tree absorbs carbon dioxide from the atmosphere, stores the carbon, and releases the oxygen. As the tree grows, it stores more and more carbon.
What is carbon pool?
A carbon pool is a reservoir with the capacity to store and release carbon, such as soil, terrestrial vegetation, the ocean, and the atmosphere.
3 ways carbon atoms return to the nonliving part of the carbon cycle?
Decomposition of dead organisms releases carbon back into the atmosphere and soil. Burning of fossil fuels releases stored carbon back into the atmosphere as carbon dioxide. Weathering of rocks can release carbon into the soil and ocean, where it can be stored for extended periods.
How does carbon enter the biotic part of the ecosystem namely plants from the atmosphere and how does it enter the soil?
Carbon enters the biotic part of the ecosystem primarily through the process of photosynthesis, where plants absorb carbon dioxide (CO2) from the atmosphere and convert it into organic compounds using sunlight. This carbon is then incorporated into plant tissues. When plants die or shed leaves, or when they are decomposed by microorganisms, carbon is released back into the soil as organic matter, enriching the soil with carbon compounds. Additionally, some carbon can enter the soil directly through root exudates released by living plants, which also contribute to soil carbon content.
How much of the earth's carbon is stored in the soil?
About 2,500 gigatons of carbon are estimated to be stored in the Earth's soil. This amount is roughly three times more than the carbon currently in the atmosphere. Soil carbon plays a crucial role in regulating the global carbon cycle and climate.

Does Soils emit carbon dioxide into the atmosphere?
Yes, I think soil can emit carbon dioxide into the atmosphere.
How does carbon enter the soil and what processes are involved in its transfer from the atmosphere to the ground?
Carbon enters the soil through a process called carbon sequestration, where plants absorb carbon dioxide from the atmosphere during photosynthesis and store it in their tissues. When plants die and decompose, the carbon is released into the soil. Additionally, carbon can also enter the soil through the decomposition of organic matter and through the activities of soil organisms. Overall, the transfer of carbon from the atmosphere to the ground involves photosynthesis, plant decomposition, and soil processes.
What is the specific component in the soil that releases gaseous carbon back into the atmosphere?
The specific component in soil that releases gaseous carbon back into the atmosphere is organic matter.
How does carbon get into the soil and what are the processes involved in its transfer?
Carbon enters the soil through a process called carbon sequestration, where plants absorb carbon dioxide from the atmosphere during photosynthesis and store it in their tissues. When plants die and decompose, the carbon is released into the soil. Additionally, organic matter such as dead leaves and roots also contribute to carbon in the soil. Microorganisms in the soil break down this organic matter through decomposition, releasing carbon dioxide back into the atmosphere. This cycle of carbon transfer between plants, soil, and the atmosphere is known as the carbon cycle.
How does carbon move from the atmosphere into the soil?
Carbon moves from the atmosphere into the soil through a process called carbon sequestration. This occurs when plants absorb carbon dioxide from the air during photosynthesis and store it in their tissues. When plants die and decompose, the carbon is released into the soil. Additionally, some carbon is directly absorbed by the soil through the breakdown of organic matter and the activities of soil microorganisms.
How does carbon return to the earth's atmosphere from the soil?
Decomposition.
How much carbon does soil store?
Soil stores a significant amount of carbon, with estimates suggesting it holds two to three times as much carbon as the atmosphere. This stored carbon is mainly in the form of organic matter derived from plant materials and microorganisms. Proper soil management practices, such as reducing tillage and adding organic amendments, can help enhance carbon storage in soils.
How does the carbon cycle in soil contribute to the overall balance of carbon in the environment?
The carbon cycle in soil plays a crucial role in maintaining the balance of carbon in the environment. Soil acts as a storage reservoir for carbon, absorbing carbon dioxide from the atmosphere through plant photosynthesis and storing it in organic matter. This stored carbon can be released back into the atmosphere through processes like decomposition and respiration. By cycling carbon through the soil, it helps regulate the amount of carbon dioxide in the atmosphere, which is important for maintaining a stable climate and overall balance of carbon in the environment.
Where does the stuff the tree is made of come from?
About half the body weight of a tree is carbon. The tree absorbs carbon dioxide from the atmosphere, stores the carbon, and releases the oxygen. As the tree grows, it stores more and more carbon.
What is soil carbon sequestration?
Soil carbon sequestration is a process that is being used to try to to 'store' all the extra carbon that is being released into the atmosphere. There are lots of different ideas about how to do it. One way they are trying to do is by turning biomass into charcoal (which retains the CO2). The charcoal is then plowed into agricultural soil, burying the carbon dioxide.
