We are cutting down forests (deforestation). This is making the problem worse because the trees take up the carbon dioxide (during photosynthesis). when the tree dies, they release carbon dioxide back to the atmosphere.

carbon is moved back into the atmosphere as carbon dioxide.
Photosynthesis!
Carbon is returned to the atmosphere through processes like respiration by living organisms, decomposition of organic matter, and combustion of fossil fuels. When organisms respire, they release carbon dioxide back into the atmosphere. Decomposition of dead organic matter also releases carbon dioxide, while burning fossil fuels releases carbon that has been stored underground back into the atmosphere.
Burning fossil fuels, deforestation, and land use changes such as agriculture all release carbon stored in plants and soil back into the atmosphere as carbon dioxide. Industrial processes and activities like cement production also contribute to carbon emissions.
Yes, when you cut down a tree and it decomposes or is burned, the carbon stored in the tree is released back into the atmosphere as carbon dioxide. This contributes to the increase of carbon dioxide levels in the atmosphere, a greenhouse gas that contributes to climate change.
Some non-human activities that release carbon into the atmosphere as CO2 during the carbon cycle include volcanic eruptions, wildfires, and the decomposition of organic matter in soils. These processes release carbon that has been stored in rocks, vegetation, or soil back into the atmosphere.
Producers, such as plants, remove carbon dioxide from the atmosphere during photosynthesis, converting it into organic carbon. This helps regulate the amount of carbon dioxide in the atmosphere. However, deforestation and land-use changes can release stored carbon back into the atmosphere, contributing to an increase in carbon dioxide levels and impacting the carbon cycle.
Burning fossil fuels and deforestation are two major human activities that increase the amount of carbon dioxide in the atmosphere, thus acting as a carbon source. When fossil fuels are burned, they release carbon dioxide, and when forests are cleared, the trees that once stored carbon release it back into the atmosphere.
When plants die or are burned, they release carbon dioxide gas back into the atmosphere. This process is known as respiration or combustion, and it is a part of the carbon cycle.
Carbon is returned to the atmosphere primarily through processes such as respiration, decomposition, and combustion. During respiration, animals and plants release carbon dioxide (CO2) as they convert glucose and oxygen into energy. Decomposition of organic matter by microbes also releases CO2 as they break down dead plants and animals. Additionally, the burning of fossil fuels and biomass for energy contributes significantly to the release of carbon back into the atmosphere.
Living things add carbon to the atmosphere through respiration, where they release carbon dioxide as a byproduct of metabolism. Additionally, when living organisms decompose after death, carbon stored in their bodies is also released back into the atmosphere. Human activities such as deforestation and burning of fossil fuels also contribute to the release of carbon into the atmosphere.
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.
