Final answer:
Fungi transfer energy to decaying matter and recycle nutrients in an ecosystem.
Step-by-step explanation:
**Fungi** play an important role in an ecosystem by **transferring energy to decaying matter**. They are decomposers, breaking down dead organic material and recycling the nutrients back into the soil. For example, when a tree falls in a forest, fungi break down the wood and release nutrients that can be used by other organisms. This process is crucial for nutrient cycling and maintaining the balance of an ecosystem.
