Which of the following adds carbon dioxide to the carbon cycle on the planet Earth?Volcanic actionRespirationPhotosynthesisDecay of organic matterSelect the correct answer using the code given below.

Accepted Answer

The carbon cycle is a crucial process that involves the movement of carbon among the atmosphere, oceans, soil, and living organisms. Several natural processes contribute to the addition of carbon dioxide (CO2) into this cycle:Volcanic action: Volcanic eruptions release significant amounts of carbon dioxide into the atmosphere.Respiration: All aerobic organisms, including humans, release carbon dioxide as a byproduct of respiration.Photosynthesis: This process, performed by plants, algae, and some bacteria, actually removes carbon dioxide from the atmosphere, rather than adding it.Decay of organic matter: The decomposition of dead organisms by microbes releases carbon dioxide back into the atmosphere.In summary, the processes that add carbon dioxide to the carbon cycle are volcanic action, respiration, and decay of organic matter.Source: 11th NCERT: Geography Chapter
