The carbon cycle is an important process that shows how carbon moves between the air, water, land, and living things on Earth. Most of the carbon in the air is in the form of carbon dioxide (CO₂), which gets released when things like animals breathe or when we burn fossil fuels like coal and oil.
Plants and algae play a big part in the carbon cycle because they take in CO₂ during a process called photosynthesis. They turn that carbon dioxide into food for themselves. Animals then get their carbon by eating plants or other animals. When animals breathe out, they release CO₂ back into the air.
When plants and animals die, tiny organisms called decomposers break them down. This process puts carbon back into the soil and the air. In water, plants also take in carbon, and over time, some of that carbon gets stored in rocks and fossil fuels.
When we burn fossil fuels or when volcanoes erupt, they release carbon back into the air, which can affect our climate and the balance of ecosystems. Learning about the carbon cycle is really important for understanding and solving environmental problems!
