Somebody: The main subject of the passage is fungi.
Wanted: The main purpose or role of fungi is to decompose organic material, such as fallen leaves, dead trees, and animal remains, thereby recycling nutrients back into the soil for other plants to utilize.
But: Fungi have unique features that distinguish them from plants; they do not rely on sunlight for energy but instead absorb nutrients from decaying materials. Additionally, they form extensive underground networks called mycelium that connect the roots of various plants.
So: This mycelial network is crucial as it allows for the sharing of nutrients and information among plants, fostering growth and resilience in ecosystems.
Then: As a result, fungi not only support individual plant health but also enhance overall biodiversity and ecosystem stability, while also playing a significant role in health and medicine through their various applications.
