An organism that feeds on decaying plant or animal matter is called what?

• A. Scavenger
• B. Herbivore
• C. Carnivore
• D. Detritivore

Answer: (A)

Feeding on decaying organic matter is described by the term detritivore. Detritivores actively ingest detritus—dead and decaying plant and animal material—and break it down inside their bodies, helping release nutrients back into the ecosystem. This makes them a key part of nutrient cycling, especially in soil and leaf litter. This differs from scavengers, which are animals that feed on dead animals (carrion). Herbivores eat living plants, and carnivores eat other living animals. Since the question emphasizes matter that is decaying and includes both plant and animal sources, detritivore is the best fit. Examples include organisms like certain earthworms and millipedes, which consume detritus and contribute to decomposition and soil health.
