What is a Decomposer? Examples of Decomposer?

In this blog post, we are going to learn about decomposers. A decomposer recycles dead plants and animals. When the plant’s and animals’ dead bodies stand, they become food for decomposers.

An example of an animal decomposer is an earthworm. Earthworms eat dead plants and animals. The waste that earthworms leave behind is rich in nutrients. Nutrients help plants to grow. Some bacteria are decomposers too.

As a decomposer, bacteria help to turn dead organisms into nutrients. Fungi are another type of decomposer. Mushrooms are a type of fungi. Molds and mildew are examples of fungi. Decomposers like living things get energy from food to better understand.

How living things get the energy we use in a food chain?

A food chain shows the relationship between the plants and animals in an ecosystem. All food begins with the sun. The sun provides the energy for everything on our planet. Plants are procedures. Procedures are at the beginning of a simple food chain. Plants get energy from the sun.

Next in the food chain are consumers. Consumers are herbivores, carnivores, and omnivores. When plants and animals die, they become the food for decomposers like dung beetles and leaf cutter ants. Decomposers like mushrooms can start with an old dead log or fallen leaves and recycle the material into rich soil for new plants to grow. All living things depend on each other.

Breaking down Materials

A decomposer is an organism that smashes down organic materials from dead organisms to acquire energy.

These organisms are almost living recycling plants. Fungi, worms, and bacteria are all examples of decomposers. The dead thing they consume is called detritus, which means “garbage”.

They are exceptionally important for nutrient cycling. Consumers will bar the energy attained from their prey in their bodies. When consumers starve, decomposers rot muscle and skin tissue to recede the minerals and resources back to the ecosystem for further usage.

What Things Do Decomposers Recycle?

Nitrogen, phosphorus, and carbon are all nutrients essential to the attainment of an ecosystem. All three can be found in rotting plant and animal matter. Decomposers influence vital roles in ecosystems by converting nutrients to protect other organisms’ alive.

Examples of Decomposers in Aquatic Ecosystems

Aquatic decomposers inhabit water-based environments that are oceanic or freshwater.

Examples of Decomposers in Oceans

There are more decomposers in tropic oceans, like the Pacific, because of the warmer temperatures. Most marine decomposers are bacteria.

Christmas tree worm


Granulated sea star


Sea urchin

Tube worm

Examples of Decomposers in Freshwater

Freshwater decomposers are mainly bacteria that are commonly found at the bottom of lakes, ponds, or rivers.


Trumpet snail

Water mold


Examples of Decomposers in Terrestrial Ecosystems

Terrestrial decomposers inhabit the land in all various types of ecosystems. The dead plants and animals they expend are called detritus.

Examples of Forest Ecosystem Decomposers

Decomposers in the forest are generally found on the forest floor.







Slime mold


Banana Slug


Examples of Desert Ecosystem Decomposers

You won’t get many decomposers in deserts because they generally like moist areas. Many of the desert decomposers you can get are insects.

Dung beetle



Saharan silver ant

Examples of Grassland Ecosystem Decomposers

Grassland decomposers can sometimes be seen in forests or deserts since those are the same environments.



Turkey tail mushroom

Examples of Mountain Ecosystem Decomposers

Mountain decomposers are also found in forests because they can occur in similar environments.

Bolete mushroom

Mountain pine bark beetle
