Answer 2

Explanation:

When forests catch fire then oxygen present in the atmosphere is used by the fire which results in the formation of carbon dioxide gas.

Whereas decomposition of organic matter is a biological process in which soil organisms like earthworms, ants etc bring both chemical and physical changes. Hence, during this process energy, plant nutrients, carbon dioxide etc are produced.

On the other hand, a volcanic eruption is the flow of ash and stream of gas into the atmosphere at several miles height. This eruption releases water vapor and toxic gases like sulfur dioxide, carbon dioxide, hydrogen sulfide etc.

Thus, we can conclude that out of the given options phenomena which releases $CO_{2}$ into the atmosphere are as follows.

• forest fires

• decomposition of organic matter

• volcanic eruptions
