Final answer:
Plants prevent erosion by holding the soil in place with their roots, providing shade, and adding nutrients through rotting leaves.
Step-by-step explanation:
Plants prevent erosion through various mechanisms. Firstly, their roots hold the soil in place, preventing it from being washed away by water or blown away by wind. Additionally, the shade created by plants reduces the impact of raindrops, which helps to protect the soil. Furthermore, rotting leaves from plants contribute to the nutrient content of the soil, which promotes plant growth and helps to stabilize the soil.
