The role of the decomposer in any ecosystem is to recycle nutrients once organisms die and nutrients in waste.


The main role of the decomposer in any ecosystem is to recycle nutrients once organisms die and recycle nutrients in waste. These nutrients are then released into the ecosystem and are available again for use.

Thus, decomposers make nutrients available again but their role is also important in terms of space. They free up the physical space an dead organisms takes up.

Decomposers help recycle what used to be in our ecosystem so life can continue.


When a plant or an animal dies, fungi and or other types of bacteria automatically respond to the change in the environment and start to decompose that matter. This is very important in our ecosystem. Here are some reasons why:

  • When a log rots due to decomposition from a fungus, it creates a home for wildlife.
  • Carbon is usually built up inside an organism. Decomposers help by releasing all this built up energy.

Although decomposition can be quite disgusting, it's a magnificent occurrence. Decomposers help release energy built up inside a plant or animal so that it can be recycled and then re-used in other organisms. For instance, when old leaves decompose, they create humus, a very fertile type of soil. This helps nourish the tree and keep it living.

This is where symbiotic relationships derives from. A symbiotic relationship is defined as the interaction between two or more organisms, in which all of them survive off each other. A tree and fungus may have symbiotic relationship because the tree provides safety and nutrients to the fungus.
