Mycorrhizal fungi play a vital role in plant ecosystems by forming symbiotic relationships with plant roots. These fungi enhance nutrient and water absorption for plants, particularly in nutrient-poor soils, by increasing the root surface area. In return, plants provide fungi with carbohydrates produced through photosynthesis. This mutualistic relationship benefits the overall health and growth of plants, contributing to biodiversity and ecosystem stability. Mycorrhizal networks also facilitate nutrient exchange between different plants, supporting the resilience and functionality of plant communities.
