Sr. No. Grazing food chain Detritus food chain
1. A grazing food chain is the one where the main source of energy is the producers or green plants.  A detritus food chain is the one where the main source of energy is the dead remains of organisms.
2. The grazing food chain releases energy into the environment. The detritus food chain uses energy from the environment.
3. The grazing food chain is large. The detritus food chain is small.
4. A Grazing food chain consists of microorganisms. The detritus food chain consists mostly of microorganisms.
5. The food chain adds energy to the ecosystem. It recovers food energy from detritus and prevents waste.
6. The food chain connects inorganic nutrients. The food chain serves to release inorganic nutrients into the cycle pool.
