Two non-human activities by which carbon can enter the atmosphere as CO2 during the carbon cycle are volcanic eruptions and wildfires. Volcanic eruptions release carbon dioxide stored in magma into the atmosphere, contributing to natural greenhouse gas levels. Wildfires release carbon stored in vegetation and organic matter back into the atmosphere as carbon dioxide when they burn.
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.
The burning of fossil fuels in activities such as transportation, electricity generation, and industry is a major process that adds carbon dioxide to the atmosphere. Deforestation also contributes to increased atmospheric carbon dioxide levels by reducing the number of trees that can absorb CO2 during photosynthesis.
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.
During the winter months, carbon dioxide levels increase because of reduced plant growth and increased human activities like burning fossil fuels for heating, which release more CO2 into the atmosphere.
During winter, there is more carbon dioxide in the atmosphere because plants go dormant and release less oxygen through photosynthesis, while human activities like heating and transportation produce more carbon dioxide.
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.
Plants and trees absorb carbon dioxide during the process of photosynthesis. Additionally, oceans act as carbon sinks by absorbing and storing carbon dioxide from the atmosphere. Human activities such as afforestation, reforestation, and carbon capture and storage technologies also help in removing carbon dioxide from the atmosphere.
When living organisms die, they decompose, releasing carbon into the soil and air. Additionally, during respiration, organisms release carbon dioxide into the atmosphere. Human activities like burning fossil fuels also contribute to the release of carbon dioxide into the atmosphere.
Carbon can be obtained from various sources, such as the atmosphere, living organisms, fossil fuels, and carbon-containing minerals. Plants absorb carbon dioxide from the air during photosynthesis, which is one way carbon enters the food chain. Additionally, human activities, such as burning fossil fuels and deforestation, release carbon dioxide into the atmosphere.
Volcanic eruptions release CO2 into the atmosphere when magma reaches the Earth's surface. Deforestation and land use changes can release carbon stored in vegetation and soil into the atmosphere as CO2.

carbon dioxide
Photosynthesis uses carbon dioxide as a raw material where carbon dioxide is fixed into organic molecules. This process lowers the level of carbon dioxide in the atmosphere. The seasonal fluctuation of carbon dioxide levels during a year may be caused by increased photosynthesis during spring and summer.
The burning of fossil fuels in activities such as transportation, electricity generation, and industry is a major process that adds carbon dioxide to the atmosphere. Deforestation also contributes to increased atmospheric carbon dioxide levels by reducing the number of trees that can absorb CO2 during photosynthesis.
