Point out the differences between a grazing and detritous food chain

The two chain begin different. The grazing chain begins with the energy entry from an inorganic source; the detritus chain receives energy from organic source (i.e. decaying leaves). But both the chains end up similarly i.e. carnivorous eating lower level animals. The two food chains i.e. grazing and detritus are ultimately linked to the same energy source i.e. solar radiation.
