Solution
The correct option is C Assertion is correct but Reason is incorrect
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. These include bacteria, fungi, protozoans. In a terrestrial ecosystem, detritus food chain is a major conduit for energy flow. Dead organic matter is the direct source of energy supply in detritus food chain.Thus, the correct answer is 'Assertion is correct but Reason is incorrect.'
