The ecological role of fungi in ecosystems is multifaceted, as they participate in nutrient cycling, decomposition, and symbiotic relationships. Fungi break down organic matter, recycling essential nutrients back into the soil, which supports plant growth. Additionally, they form mycorrhizal associations with roots, facilitating nutrient uptake for plants while receiving carbohydrates in return. This relationship enhances ecosystem productivity and resilience. Fungi also play a role in bioremediation, helping to detoxify contaminated environments. Overall, their contributions are vital for maintaining healthy ecosystems.
