The Carbon Cycle

HOW DOES THE CARBON CYCLE WORK ON LAND?
The Carbon Cycle is all around us, carbon is in all living things such as plants, shells, fish, reptiles, mammals, humans and much, much more. Carbon is found in some non-living things as well like rocks, fossil fuels and rubbish bins.
The carbon cycle is an important part of Earth because it keeps us living. Our bodies are made up of carbon and we would be in a lot of trouble if carbon did not exist.
Photosynthesis is a very important part of the Carbon Cycle. Trees capture the sun’s energy to use carbon to make food. We breathe out carbon dioxide and trees breathe it in, we breathe in oxygen the trees give us.  When leaves fall off trees, they float down the river,  which flows downstream, to a lake or ocean, where it is then disintegrated and the Carbon sinks to the bottom of  the sea or lake which is called transportation. 
Animals are non-photosynthetic creatures. Which means they are not able to create their own food, so they eat plants instead.  Then the carbon from the plant goes into the the animal,  and  eventually the animal dies and turns into fossil  fuels this is called disintegration and compaction.
The humans impact on the carbon cycle is getting worse, we are cutting down more and more trees by the minute and creating more fossil fuels. If we do not stop now the world will end quickly.
So to conclude the carbon cycle is a complex cycle. That occurs just about anywhere, and is all around us. It starts with photosynthesis, then turns to respiration, then becomes decomposition, transforms into transportation, then lastly compaction.
