Insects are a diverse group of small arthropods that belong to the class Insecta within the phylum Arthropoda. Characterized by their three-part body structure comprising a head, thorax, and abdomen, insects also possess a pair of antennae and, typically, three pairs of legs. They are the most numerous and varied group of organisms on Earth, with millions of species described and many more yet to be discovered. Insects can be found in a wide range of ecosystems, from forests and deserts to freshwater and marine environments.
Insects play crucial roles in maintaining ecological balance. They are integral to processes such as pollination, decomposition, and nutrient cycling. Many insects serve as vital food sources for other wildlife, including birds, mammals, and amphibians. Additionally, their interactions within food webs contribute to the health of ecosystems, making them essential for both biodiversity and human agriculture.
