Insects are a diverse group of small, six-legged arthropods that play a crucial role in ecosystems worldwide. They have three body segments (head, thorax, and abdomen) and often possess wings, allowing them to fly. Insects are highly adaptable and can be found in various habitats, from forests to deserts. They serve as pollinators for many plants, decomposers, and essential food sources for other animals. While some insects can be harmful as pests, many are beneficial, aiding in agriculture and maintaining ecological balance. Their remarkable diversity and ecological importance make them one of the most successful and abundant animal groups on Earth.
