The carbon cycle is the biochemical cycle by which carbon is exchanged between living organisms and the environment. The carbon which can be utilized by these organisms is mainly carbon dioxide in the atmosphere. Carbon dioxide can be transformed into organic carbon in a plant through photosynthesis, before entering an animal’s body through food chains. Oceans can store a massive amount of carbon dioxide, too. The carbon in a living organism can become carbon dioxide again through respiration and decomposition. The carbon then dissipates into the air - this is the carbon cycle. Human activities such as burning fossil fuel and deforestation lead to an increase in carbon emissions. These activities also affect carbon storage, bringing immense impacts to the carbon cycle.
