1. In grazing food chain, the energy is transferred from producers to consumers.
2. The autotrophs convert inorganic matter into organic compounds which is then transferred in food chain or food web.
3. In detritus food chain energy is obtained from organic matter or detritus generated in trophic levels of the grazing food chain.
4. Detritus such as dead bodies of animals or fallen leaves, which are then eaten by decomposers or detritivores.
5. These detritivores can also be consumed in grazing food chain by secondary consumers or predators.
6. When decomposers convert organic matter back into inorganic substances, the autotrophs use these minerals again.
7. In this way GFC and DFC are connected to each other in cyclic and mutual exchanges.
