An "insekt" is a small, six-legged creature that belongs to the class Insecta. Insects are characterized by their three main body parts: the head, thorax, and abdomen. They have a hard outer shell called an exoskeleton and often possess wings, allowing many species to fly. Common examples of insects include bees, ants, and butterflies. Insects play vital roles in ecosystems, such as pollination, decomposition, and serving as food for other animals. They are found in nearly every habitat on Earth, from forests to deserts. With over a million known species, insects are the most diverse group of animals on the planet.
