Answer:

Decomposers recycle essential nutrients back into an ecosystem

Explanation:

An ecosystem works thanks to the constant transformation of energy. The role of the decomposers will be to transform energy into something useful in the ecosystem. For example, The bacteria which will rotten the apples that fall from a tree onto the ground are recycling or making available this energy for other organisms to use it. As part of this example, the essential nutrients of the apples will be available to be reabsorved by the roots of the apple tree thanks to the transformation of energy done by the bacteria in the apples.  

Answer: • Decomposers recycle essential nutrients back into an ecosystem.

Explanation:

The decomposers are the small microorganisms which can be found in the soil habitat. These organisms obtain energy by break down of organic matter generated after the death of plants, animals and their residual matter. Through the process of decomposition the decomposers release nutrients such as nitrogen and carbon back to the environment. These nutrients are absorbed by the plants through soil. This way the nutrients are recycled in an ecosystem by decomposers.
