Mycorrhizal networks are underground systems formed by the symbiotic relationship between fungi and the roots of plants. These networks allow for the exchange of nutrients, water, and even chemical signals between different plants, enhancing their growth and resilience. Through these connections, plants can share resources, such as carbon and nitrogen, which can be crucial for survival, especially in nutrient-poor soils. Mycorrhizal networks also help in the communication between plants, enabling them to respond to environmental stresses or threats, such as pests or diseases.
