Decomposers (or saprotrophs) are organisms that consume dead organisms, and, in doing so, carry out the natural process of decomposition. Like herbivores and predators, decomposers are heterotrophic, meaning that they use organic substrates to get their energy, carbon and nutrients for growth and development. Decomposers use deceased organisms and nonliving organic compounds as their food source. The primary decomposers are bacteria and fungi.
[edit] Importance of the function in the ecosystem
When a plant or animal dies, it leaves behind nutrients and energy in the organic material that comprised its body. Scavenger and detritivores can feed on the carcasses or litter, but they will inevitably leave behind a considerable amount of unused energy and nutrients. Unused energy and nutrients will be present both in the unconsumed portions (bones, feathers or fur in the case of animals, wood and other indigestable litter in the case of plants) and in the feces of the scavengers and detritivores. Decomposers complete decomposition by breaking down this remaining organic matter. Decomposers eventually convert all organic matter into carbon dioxide (which they respire) and nutrients. This releases raw nutrients (such as nitrogen, phosphorus, and magnesium) in a form usable to plants and algae, which incorporate the chemicals into their own cells. This process resupplies nutrients to the ecosystem, in turn allowing for greater primary production.
An example of a decomposer is saprotrophic fungus; it breaks down dead trees, harvesting the energy stored therein.
Although decomposers are generally located on the bottom of ecosystem diagrams such as food chains, food webs, and energy pyramids, decomposers in the biosphere are crucial to the environment. By breaking down dead material, they provide the nutrients that other organisms need to survive. As decomposers feed on dead organisms, they leave behind nutrients. These nutrients become part of the soil. Therefore, more plants can grow.

What else can I help you with?
What are the benefits of decomposers?
They return nutrients to the environment.
What are most bacteria?
Most Bacteria are decomposers or producers, or consumers
In an ecosystem nutrients would be recycled if they were transferred directly from hebivores to carnivores to?
In an ecosystem, nutrients would be recycled if they were transferred directly from herbivores to carnivores to decomposers. Decomposers break down organic matter, releasing nutrients back into the environment where they can be taken up by plants and reused by herbivores. This cycle ensures that nutrients are continually circulated within the ecosystem.
How do decomposers help in the process of photosynthesis?
Decomposers break down dead organisms and organic matter into nutrients like nitrogen and phosphorous. These nutrients are then released into the soil, which can be absorbed by plants to help them grow and undergo photosynthesis. Therefore, decomposers indirectly support photosynthesis by recycling essential nutrients back into the ecosystem.
Who are the decomposers in most ecosystems?
They are the bacteria and fungi.
You would probably find the most decomposers in the soil layer called?
You would find the most decomposers in the topsoil layer. This layer is rich in organic matter, making it an ideal environment for decomposers like bacteria, fungi, and insects to break down and recycle nutrients from dead plants and animals.
Which soil layer are most decomposers found?
topsoil.
What are decomposers organism group in to?
Most of them are bacteria and fungi.
Animals that are decomposers?
Most decomposers are insects. Flies, maggots, beetles, ants and roaches are forms of insect decomposers. Other decomposers known as scavengers are vultures, hyenas, and possums.
Which organism recycles waste and dead material consumer or decomposers?
Decomposers are the organisms responsible for recycling waste and dead material, breaking them down into simpler components that can be used by other living organisms. Consumers are organisms that directly feed on other organisms for energy.
What types of decomposers are found in a cold desert?
Fungi and bacteria are the decomposers found in most any biome, including in cold deserts.
Which organism gets food energy directly from both plants and animals?
the foxxxy mamma doo girlll .. shoot !
