Distinguish between(a) Grazing food chain and detritus food chain

Answer»

The grazing food chain starts from the autotrophs (green plants), whereas detritus food chain begins from the detritivores.

In grazing food chain the energy is taken from the sunlight as green plants prepare food in the presence of it while in detritus food chain the main energy source is remain of detritus.

In grazing food chain macroscopic organisms are involved, on the other hand, in detritus food chain, subsoil organisms are involved, which can either be macroscopic or microscopic.
