Fungi play a crucial role in nutrient cycling in nature by breaking down organic matter, such as dead plants and animals, into simpler compounds. This decomposition process releases nutrients like carbon, nitrogen, and phosphorus back into the soil, making them available for other organisms to use for growth and development. Fungi also form symbiotic relationships with plants, such as mycorrhizae, where they help plants absorb essential nutrients from the soil. Overall, fungi contribute significantly to the recycling of nutrients in ecosystems, making them essential for maintaining a healthy and balanced environment.
