Detritus food chain is the type of food chain in which the dead organic matter called detritus are utilized to maximum level and there is minimum wastage of organic material. In this, the primary source of energy is dead organic matter, that is leaves, plant parts and dead animals. The primary consumers are called as detritivores.
Solution. Verified by Toppr. Detritus food chain begins with the dead organic matter. It is made up of decomposers (saprotrophs) which are heterotrophic organisms. For example, fungi and bacteria. They meet their energy and nutrient requirements by degrading dead organic matter or detritus.
I. Detritus food chain begins with dead organic matter II. In aquatic ecosystem, detritus food chain is the major conduit for energy flow III. In terrestrial ecosystem a larger fraction of energy flows through grazing food chain IV. Producers belong to the first trophic level of the food chain

Detritus food chains is the type of food chain that ensures maximum utilization and minimum wastage of available material. Detritus food chain begins with dead organic matter. When organisms die then their body form a source of energy and raw materials for other organisms. The amount of energy present is high in a dead organism.
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. Was this answer helpful?

The detritus food chain starts from the decomposition of organic matter and the nutrients and energy released flows to other tropic levels in step by step manner. Because there is a partial digestion of food to obtain chemical energy by microbes, a lot of organic nutrients are excreted in the form of waste.
