what is the role decomposers in ecosystem?

 Decomposers are an essential component of any ecosystem. Their main role is to recycle nutrients in dead organisms and their wastes. Most decomposers are bacteria and fungi. Without the decomposers, there could be no life, since plants would then run out of nutrients.

When a plant or animal dies, it leaves behind nutrients and energy in the organic material that comprised its body. Scavengers and detritivores can feed on the carcasses, 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 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.

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 and thrive.

Bacteria are the primary decomposers of dead animals (carrion) and are the primary decomposers of dead plant matter (litter) in some ecosystems

Decomposers help in returning the nutrients to the environment after the death of animals and plants.
Decomposers helps in recycling material to the Ecosystem.

  • They convert the complex organic substances into simple inorganic substances which acts as a manure and increases the soil fertility.
  • They prevent pollution as they decompose biodegradable waste.
  • they increase soil fertility by promoting the growth of manure

Decomposers form a very important part of our ecosystem. They are actually small micro-organisms which help in maintaining the ecological balance in our environment. 

when any living organism dies {the circulation of blood stops and the body becomes static}, decomposers start to transform the matter from complex to simpler substances. 
These decomposers act upon the dead matter and change it into simpler form and leave behind the manure which makes the soil fertile and provides suitable conditions for the plants to grow. 
As a result, the ecological cycle keeps on going.... 
It is like...... 
PLANTS 
I 
HERBIVORES 
I 
CARNIVORES 
I 
DIE AND DECOMPOSED 
BY DECOMPOSERS 
I 
SOIL 
I 
PLANTS AGAIN...... 
This is the cycle of nature in which decomposers play a very vital role. 
decomposers can easily decompose biodegradable substances but can also decompose non-biodegradable substances.it's only metals,etc. take thousands of years to get decomposed. 
bacteria is a type of decomposer...

They maintain nutrient pool of the earth by putting back various elements into the nutrient pool

Organic matter is recycled in an ecosystem by decomposers. decomposers are organisms such as bacteria and fungi that break down the organic matter in the dead bodies of plants and animals. As the decomposers feed from the dead animals, they break down the organic compounds into simple nutrients.
