The diagram of the carbon cycle given here explains the different processes that occur within it.
Explanation:
1. In G label of the cycle, the process taking place is greenhouse emission where carbon is released in the air by the man made fossil fuel using machines and factories.
2. The energy transformation that is taking place here is that the energy is going from being actively used for human consumption to the static energy which goes into the environment.
3. This process sends the carbon from the environment back to the environment so in theory it is a recycling process only.
