Detritivores are organisms that consume dead organic matter, playing a crucial role in decomposition and nutrient cycling. Earthworms break down dead plant material in the soil. Millipedes consume decaying plant matter. Woodlice, also known as roly-polies or pill bugs, feed on decaying wood and other dead organic material. Jellyfish are carnivores or filter feeders, and seahorses are typically predators of small crustaceans and fish, not detritivores.
