IELTS Task1 the carbon cycle in nature

Question

Following that, during the second main stage which is the formation of CO2 cycle, it is noticeable that carbon comes from several ways. Not only do animals and plant respire carbon but transportations and factory also release a huge amount of it. Then this carbon with the sunlight start over from the beginning and that’s when a carbon cycle is completed. 

In conclusion, all of the stages which are mentioned above describe fully the cycle of carbon in the natural environment.
