CO2 is absorbed into the atmosphere through various natural processes like plant respiration and ocean absorption. Additionally, human activities, such as burning fossil fuels and deforestation, release large amounts of CO2 into the atmosphere, contributing to increased levels of greenhouse gases.
CO2 can be removed from the air through natural processes like photosynthesis by plants, algae, and trees, which absorb CO2 and release oxygen. Additionally, carbon capture and storage technologies can be used to capture CO2 emissions from industrial processes or power plants before releasing them into the atmosphere.
Reducing CO2 emissions by using cleaner energy sources, like solar or wind power, can help decrease the amount of CO2 in the atmosphere. Additionally, promoting carbon sequestration through activities such as afforestation and reforestation can help capture and store CO2 from the atmosphere. Carbon capture and storage technologies can also trap CO2 emissions from industrial processes before they are released into the atmosphere.
There are various factors that can lead to a decrease in CO2 levels in the atmosphere, including increased uptake by plants through photosynthesis, reduced emissions from human activities such as burning fossil fuels, and natural carbon sequestration processes. However, it is important to note that overall CO2 concentrations in the atmosphere are still rising due to ongoing human activities that release large amounts of CO2.
Photosynthesis and cellular respirationcellular respiration
The balance of CO2 and O2 in the atmosphere is maintained through a process known as the carbon cycle. Plants and phytoplankton remove CO2 from the atmosphere through photosynthesis while animals and other organisms release CO2 through respiration. Overall, these processes help sustain the relative levels of both gases in the atmosphere.
CO2 is absorbed into the atmosphere through various natural processes like plant respiration and ocean absorption. Additionally, human activities, such as burning fossil fuels and deforestation, release large amounts of CO2 into the atmosphere, contributing to increased levels of greenhouse gases.
The carbon cycle is a natural biogeochemical cycle whereby carbon as CO2 is transferred from the atmosphere to the land and ocean, where it resides in another form before returning to the atmosphere as CO2. The principal processes involved in transfer from the atmosphere are the dissolution of CO2 in the oceans and the uptake of CO2 by the photosynthesis of green plants. The processes involved in return to the atmosphere are the release of CO2 from the ocean in regions in which the surface of the ocean has become saturated with CO2 and the oxidation of organic matter by respiration or fire, which essentially reverses the photosynthetic process: 6CO2 + 12H2O ⇔ C6H12O6 + 6O2 + 6H2O
Breathing (though it does not release a great deal of co2) , at night, plants take in oxygen and give out carbon di- oxide , volcanic eruptions , and the formation of fossil fuels.

Photosynthesis in plants absorbs CO2 from the atmosphere, while respiration from animals and decomposition of organic matter releases it back. These two processes work in balance to keep the concentration of CO2 relatively stable in the atmosphere.
The burning of fossil fuels is the largest contributor to increased levels of CO2 in the atmosphere. This includes activities such as driving cars, generating electricity, and industrial processes, which release CO2 as a byproduct.
CO2 in the atmosphere exists throughout different layers, but it is mainly transported to the upper atmosphere through atmospheric circulation and mixing processes. Some CO2 molecules can also be carried to the upper atmosphere by volcanic eruptions or in the form of methane, which can be oxidized into CO2 at higher altitudes.
Respiration (breathing). This is carbon dioxide recently removed from the atmosphere, so does not contribute to global warming.Burning fossil fuels (coal, oil and natural gas). This is carbon dioxide that has been underground for 300 million years, so it does contribute to global warming.
Photosynthesis does not.A:The photosynthesis process in vegetation, plants and trees does release CO2. Not only that, it also captures it again from the atmosphere. The photosynthesis process is part of a larger natural process called the Carbon Cycle. In this cycle, oceans release and capture CO2 too.
CO2 can be removed from the air through natural processes like photosynthesis by plants, algae, and trees, which absorb CO2 and release oxygen. Additionally, carbon capture and storage technologies can be used to capture CO2 emissions from industrial processes or power plants before releasing them into the atmosphere.
CO2 levels are higher now primarily due to human activities such as burning fossil fuels, deforestation, and industrial processes. These activities release large amounts of carbon dioxide into the atmosphere, causing an imbalance in the natural carbon cycle and leading to increased concentrations of CO2 in the atmosphere.
