The carbon cycle is a complex series of processes through which all of the carbon atoms in existence rotate. The same carbon atoms in your body today have been used in countless other molecules since time began. The wood burned just a few decades ago could have produced carbon dioxide which through photosynthesis became part of a plant. When you eat that plant, the same carbon from the wood is now in you.

1. **Carbon Dioxide in the Atmosphere**: The cycle begins with Carbon dioxide (CO2) in the atmosphere. This is the starting point of the carbon cycle.

2. **Photosynthesis**: Plants take in this CO2 during photosynthesis, a process in which the sunlight's energy is used to convert CO2 into glucose (a type of sugar). This process not only helps plants grow, but it also plays a crucial role in the carbon cycle by removing CO2 from the atmosphere and storing it in plants.

3. **Consumption by Animals**: When animals eat these plants, the carbon from the plant becomes part of the fats and proteins in the animal. Some of this carbon is breathed out as CO2, but some of it is used in the growth and repair of the animal's body.

4. **Decomposition**: When plants and animals die, their bodies, wastes, and remains are broken down by bacteria and fungi (decomposers). This process releases carbon back into the atmosphere as CO2. This process is known as decomposition.

5. **Fossil Fuels**: Some of the carbon that is in plants and animals doesn't return to the atmosphere right away. If the conditions are right, over many years, the remains of plants and animals can be turned into fossil fuels (coal, oil, and natural gas). When humans burn fossil fuels, most of the carbon quickly ends up back in the atmosphere as CO2.

6. **Return to Atmosphere**: The CO2 is then released back into the atmosphere through respiration, decay, and combustion of organic matter, completing the cycle.

This is a simplified version of the carbon cycle. In reality, it is much more complex and there are many more 'reservoirs' where carbon can be stored. For example, carbon is also dissolved in the ocean and stored in rocks and sediments.
