Solution
The correct option is D Decomposers
Detritus is defined as dead and decaying organic matter that includes fallen leaves, dead plant parts and animals. It is the primary source of energy in the detritus food chain in which the microbes such as protozoans, bacteria and fungi help in the breaking down of the complex organic matter. They are called decomposers. Detritus food chain hence helps in soil replenishment by adding nutrients to the soil. This detritus is eaten by invertebrates, which are in turn eaten by vertebrates. Hence a detritus food chain begins with decomposers. Thus the correct answer is option D.
