The diagram below shows the cycle of carbon in nature.
Overall, the carbon cycle has a few processes. Carbon dioxide is used for plant respiration and animal respiration. after that carbon cycle also used by trees. The complete step will be explained in the next paragraph.
The first step, carbon dioxide in the atmosphere, is used by plants for photosynthesis. After that the trees will be used as food by animals. In the next process, the animals will be used by trees as fertilizer. After that the composition will be fossils. Animals and plants will use carbon dioxide for respiration.
The next cycle, animals will sediment on land and become fossils. After that, the fossils will be used in factories for their machines. And then the machines produce fumes. The pollution will become carbon dioxide. This factory will produce pollution and then it will used by animal for respiration. it is bad for environment to use carbon dioxide.
