Decaying organic life emits a large portion. Naturally occurring fires also add a great amount of carbon dioxide. Natural respiration of animal life also gives off carbon dioxide. In total natural processes make up 94% of all carbon emissions.
The process that adds carbon from the atmosphere is known as carbon sequestration or carbon uptake. This can occur through natural processes like photosynthesis in plants, where they absorb carbon dioxide from the air and store it in their tissues. Additionally, carbon can be taken out of the atmosphere and stored through human activities like carbon capture and storage technologies.
Combustion. The burning of any material.
Breathing.Burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity.
As the olive tree grows it takes in carbon dioxide for photosynthesis, and gives out oxygen. When olive oil is burnt it gives out the carbon dioxide that it took in, so overall there is no net movement of carbon dioxide. - This is why it is said to be carbon neutral. "Carbon neutral" means generally that the activity adds no additional carbon dioxide to the atmosphere. This is in comparison to the burning of fossil fuels (coal, oil and natural gas) which do add extra greenhouse gases (carbon dioxide which has been hidden underground for 300 million years).
The gas released when trees are burned is carbon dioxide, a greenhouse gas that contributes to climate change. It is released as a byproduct of the combustion process, where the carbon stored in the tree is oxidized and released into the atmosphere.
The process that adds gases to the atmosphere is volcanic activity, which releases gases such as carbon dioxide and sulfur dioxide. The process that removes gases from the atmosphere is photosynthesis, where plants absorb carbon dioxide and release oxygen.

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.
Combustion. The burning of any material.
The combustion of fossil fuels releases carbon dioxide into the atmosphere, contributing to the greenhouse effect and global warming. This disrupts the balance of the carbon cycle by adding more carbon dioxide than natural systems can absorb, leading to increased levels of carbon in the atmosphere and oceans.
There is more carbon dioxide in the atmosphere now because we have been burning fossil fuels (coal, oil and natural gas) for more than 200 years. This burning adds long-hidden carbon dioxide, so it is too much for the carbon cycle to completely recycle.
Rotting trees add carbon dioxide (and sometimes methane) to the atmosphere.Burning trees releases carbon dioxide to the atmosphere.
Because photosynthesis is for plants and plants give off oxygen, not carbon dioxide.

Burning vegetation adds to the carbon dioxide levels in the atmosphere. However, that carbon dioxide was recently removed from the air when the plants were growing, so burning vegetation is carbon neutral.Burning fossil fuels (coal, oil and natural gas), of course, releases extra carbon dioxide that has been hidden away for 300 million years.
The process that adds oxygen to the air is called photosynthesis. During photosynthesis, plants use sunlight to convert carbon dioxide and water into glucose and oxygen. This process is crucial for maintaining the balance of oxygen and carbon dioxide in the Earth's atmosphere, which is essential for supporting life on our planet.
