Dead Animal–Maggots–Frog–Snake is an example of detritus food chain. In such a food chain, Primary consumers are ‘detritivores’ including protozoans, bacteria, fungi, etc which feed upon the detritus (dead organic matter such as fallen leaves, plant parts or dead animal bodies) saprophytically. They are in turn eaten by secondary consumers such as insect larvae, nematodes, etc. In nature, detritus food chains are indispensable as the dead organic matter of grazing food chain is acted upon by the detritivores to recycle the inorganic elements into the ecosystem.
