The earthworm is important to the farmer because it helps to improve the soil in many ways. It helps to aerate the soil by creating tunnels, which allows oxygen and water to penetrate deep into the soil. The tunnels also provide a way for roots to grow deeper, making the plants more resistant to drought. Additionally, the earthworm eats organic matter and other microorganisms in the soil, breaking them down and turning them into nutrients that plants can use. This process helps to improve soil texture and structure, making it easier for plants to grow. Finally, the earthworm helps to check soil erosion by binding soil particles together, reducing the risk of soil being washed away by heavy rain.
