The primary function of plant roots in ecosystems is to anchor plants and absorb essential nutrients and water from the soil. Roots also help stabilize the soil, preventing erosion and promoting water retention. Additionally, they interact with soil microorganisms, forming beneficial relationships that enhance nutrient availability, thus supporting overall plant health. By contributing to soil fertility and structure, plant roots play a critical role in maintaining ecosystem productivity and resilience. Their functions are essential not only for the plants themselves but also for the entire ecosystem's health.
