Land Based

First, plants and trees take carbon out of the air and use it to make their own food. Secondly, a decomposition process deposits carbon that was stored in the ground, into rocks and soil. Thirdly, burn fossil fuels to release carbon back into the air. Lastly, deforestation releases stored carbon into the atmosphere.

Water Based

First, carbon is held in the sea water. Air passes over water and some carbon is taken and stored in the air .

That is diffusion.

More steps..

Carbon in the water is taken by sea plants and they use it to make their own food, with photosynthesis.

More

Carbon is stored in the plants and the sea life eats those plants. Some carbon is released in the air by living organisms and this is called respiration. Then, cells work and give off carbon as a waste product, making it go back into the water.

And more.. :)

When living things die, they get broken down and fall to the seafloor. This is sediment. Carbon that is stored in sediment can be dissolved a bit in water or left in the Earth. Unique sea creatures can use carbon to create shells. When the creature dies, the shell will fall to the floor and become a rock. Rocks will break down and release carbon back into the water. If there is carbon in deeper parts, then the deep ocean is high in carbon content. The carbon rich water is brought to the surface using a process of ocean circulation. Then, the water can release carbon using diffusion.

What is the carbon cycle?

The carbon cycle is the cycling of carbon atoms between the atmosphere, oceans, Earth, and organisms.

Why is this important?

Two types.

The carbon cycle has 2 types;

Land based and water based.

The carbon cycle is important because all living organisms are composed of carbon compounds. So, this is an important building block of life and it is an important component of many chemical processes.
