Animals are a diverse group of living organisms that belong to the kingdom Animalia. They are characterized by their ability to move, consume organic material, and respond to their environment. Animals can be found in various habitats, from the deepest oceans to the highest mountains, showcasing a wide range of adaptations and behaviors. There are millions of species of animals, ranging from tiny insects to massive whales. They play crucial roles in ecosystems, contributing to processes like pollination, decomposition, and food webs. Understanding animals helps us appreciate biodiversity and the importance of conservation efforts to protect their habitats.
