Explanation:

• Detritus food chain is the type of food chain that starts with dead organic materials. The dead organic substances are decomposed by microorganisms. The organisms that feed on dead organic matter or detritus, are known as detritivores or decomposers. These detritivores are later eaten by predators. In the detritus food chain, the excreted products by one organism is utilized by another organism.
• The detritus food chain helps in solving inorganic nutrients.
• Compared to other kinds of food chains, the detritus food chain has much larger energy flow in a terrestrial ecosystem.

Hence both statements are correct.
