Somebody: The main subject of the passage is fungi and their role in ecosystems.
Wanted: The main purpose or role of fungi is to act as essential decomposers, breaking down organic material and recycling nutrients back into the soil for plants to use.
But: Fungi have unique features, such as not relying on sunlight for energy and forming extensive networks of mycelium that connect plants, allowing them to share nutrients and information.
So: This process of decomposition and nutrient absorption helps support plant growth and enhances the overall health and biodiversity of ecosystems.
Then: As a result, fungi play critical roles beyond decomposition, including potential contributions to medicine and helping plants endure challenging environmental conditions.
