Detritivores (also known as detrivores, detritophages, detritus feeders, or detritus eaters) are heterotrophs that obtain nutrients by consuming detritus (decomposing plant and animal parts as well as feces). ... By doing so, all these detritivores contribute to decomposition and the nutrient cycles.

What is the role of detritus?
It is now known that the ecological role of detritus is twofold. If dead organic matter is left in contact with microbes but isolated from higher organisms it will eventually decompose completely, releasing nutrient materials that are available for new cycles of plant production.
What is the role of detritus feeders in carbon cycle?
Detritus feeders feed on dead and decaying producers (plants) and consumers (animals) and return carbon dioxide to the atmosphere. They also contribute to the CO2 pool by processing dead and waste organic matter.
What is the role of detritus in an ecosystem?
In ecosystems on land, detritus is deposited on the surface of the ground, taking forms such as the humic soil beneath a layer of fallen leaves. ... Much detritus is used as a source of nutrition for animals. In particular, many bottom feeding animals (benthos) living in mud flats feed in this way.
What is detritus and why is it important?
What Is Detritus?: Detritus is organic waste material in the ecosystem. Detritus includes dead plants, animals, and feces. Detritus provides important value for the ecosystem, particularly wetlands.
Why are detritus feeders important in cycling?
Detritivores and decomposers contribute to the breakdown of all of the dead and decaying material in any ecosystem. In this way they play an important role in the cycling of nutrients and are an essential part of most biogeochemical cycles, such as the carbon cycle, nitrogen cycle and the phosphorus cycle.
Is detritus feeders a producer?
Consumers (heterotrophs) - Get their energy and nutrients by feeding on other organisms or their remains. ... Detritus Feeders - Live off of detritus or parts of dead organisms. Examples: Crabs, carpenter ants, termites, earth worms, and wood beetles.
What is detritus feeders in ecology?
Detritivores (also known as detrivores, detritophages, detritus feeders, or detritus eaters) are heterotrophs that obtain nutrients by consuming detritus (decomposing plant and animal parts as well as feces). ... By doing so, all these detritivores contribute to decomposition and the nutrient cycles.
How does detritus feeders and the process of decay done by decomposers return carbon in the atmosphere?
It is broken down by the decomposers, or detritus feeders (I), which are small animals and microorganisms that subsist on decaying matter such as fallen leaves, dead bodies, and animal wastes. ... Thus, respiration in detritus feeders (J) also returns carbon to the atmosphere.
Is detritus a primary producer?
The organisms in the trophic levels above the primary producers are heterotrophs. ... Detritus is nonliving organic material, including the remains of dead organisms, leaves, and feces. Because of how they get energy, detritivores are sometimes called decomposers.
What is the role of detritus in the swamp?
Detritus is the dead and decaying remains of plants and animals and the faecal material. It is decomposed by decomposers to release nutrients. They provide nutrients for the growth of plants in the swamp.
What does a detritus food chain start with?
The Detritus food chain (DFC) starts with detritus or dead organic matter. It is made up of decomposers which are heterotrophic organisms mainly bacteria and fungi.
Why is detritus such an important part of the food web for salt marsh mangrove and seagrass communities?
Detritus derived from vascular plants (seagrasses, marsh grasses and mangroves) contains much structural material that is indigestible to most animals. ... Bacteria associated with detritus food webs are an important mechanism for conserving nitrogen in coastal ecosystems.
What is detritus and how does it affect nutrient availability in ocean waters?
Detritus (dead organic matter) and associated nutrient inputs into the littoral zone are either allochthonous (derived from terrestrial sources) or autochthonous (aquatic sources). ... The distribution of detritus influences the availability of dissolved organic matter and nutrients for biotic uptake.
What organisms feed on detritus found in wetlands?
Nutrients released by detritus into the water and soil are assimilated by microorganisms, algae, plants, and small aquatic animals. Through this process, energy is transferred from detritus to other biotic components of a wetland. Plant litter ultimately decomposes.
What would happen if there were no decomposers?
Without decomposers, dead leaves, dead insects, and dead animals would pile up everywhere. ... Thanks to decomposers, nutrients get added back to the soil or water, so the producers can use them to grow and reproduce. Most decomposers are microscopic organisms, including protozoa and bacteria.
Why are decomposers important?
Decomposers feed on dead things: dead plant materials such as leaf litter and wood, animal carcasses, and feces. They perform a valuable service as Earth's cleanup crew. Without decomposers, dead leaves, dead insects, and dead animals would pile up everywhere.
What is the difference between scavengers and Detritivores?
For example, scavengers cannot consume bones, feathers, and fur of dead animals, and detritivores cannot consume wood and other indigestible plant materials. Organisms called saprotrophs complete the breakdown of any remaining organic matter. The main saprotrophs that decompose dead animal matter are bacteria.
