Symbiotic fungi, such as mycorrhizae, play a crucial role in plant nutrition by enhancing nutrient uptake. These fungi form mutualistic associations with plant roots, facilitating the absorption of essential nutrients like phosphorus and nitrogen. In return, plants provide the fungi with carbohydrates produced through photosynthesis. This symbiotic relationship improves overall plant health and growth, increases resistance to environmental stresses, and boosts soil structure. Thus, the presence of symbiotic fungi is essential for sustaining ecosystem productivity and maintaining plant diversity.
