Arthropods play a crucial role in various ecosystems as pollinators, decomposers, predators, and prey. They also have economic significance as pests and sources of food and medicine.

Study Tips

When studying arthropods, it's important to focus on their diverse adaptations for survival, their ecological roles, and their impact on human society. Use visual aids such as diagrams and videos to understand the anatomy and behavior of different arthropod groups.
