Answer
Arthropods can often be crop pests, impacting plants by feeding on their roots or stems, which may lead to decreased yield or damage. However, they can also contribute positively by improving soil aeration and nutrient cycling. Earthworms, on the other hand, improve drainage, aerate soil, and enhance nutrient availability by mixing soil layers, thereby playing a vital role in maintaining soil fertility.
