Knowra Detritivore Detritivore A detritivore is an organism that obtains nutrients by consuming detritus: dead plant or animal material and organic waste. Its feeding helps break this material into smaller particles.
Detritus : Dead organic material and waste derived from plants, animals, and microorganisms. It is the material detritivores consume.
Saprotrophy : A mode of nutrition in which organisms digest dead organic matter externally and absorb the resulting nutrients. It distinguishes microbial decomposition from an animal's ingestion of detritus.
Earthworm : A segmented annelid that lives in soil and often ingests soil mixed with decaying organic matter. Earthworms ingest and fragment litter while mixing organic material into soil.
Bioturbation : The disturbance and mixing of sediment or soil by living organisms. Burrowing detritivores move organic matter and alter soil structure.
Decomposition : The breakdown of organic matter into simpler substances by biological and chemical processes. Detritivores fragment material that decomposers further break down.
Scavenger : An animal that feeds on dead animals, often consuming relatively fresh carcasses. Scavengers overlap with detritivores but commonly exploit larger, fresher remains.
Millipede : A many-legged arthropod that commonly feeds on decaying leaves and other dead plant matter. Millipedes are prominent litter-feeding detritivores in many terrestrial habitats.
Soil formation : The long-term development of soil through interactions among parent material, climate, organisms, and time. Detritivore fragmentation contributes organic material to developing soils.
Decomposer : An organism, usually a bacterium or fungus, that chemically breaks down dead organic matter and absorbs its nutrients. Unlike detritivores, decomposers digest material externally and absorb dissolved products.
Herbivore : An animal that obtains food by eating living plants or algae. Detritivores consume dead organic material rather than living primary producers.
