Explanation
The dead organic matter of plants or animals is called detritus. While a part of it remains on the soil surface as litter, the other part enters the soil. Many animals such as protozoans, nematodes, insects, etc., depend on detritus and hence they are called detritivores. Even human beings are detritivores when they eat cooked food. From detritus, the chain proceeds to detritivores, then to carnivores, and finally to top carnivores.
