animals

Animals are living organisms that belong to the kingdom Animalia. They are characterized by their ability to move, respond to their environment, and consume organic material for energy. Animals vary widely in size, shape, and habitat, ranging from tiny insects to large mammals. They play critical roles in ecosystems, contributing to biodiversity, food chains, and environmental balance. Animals are classified into various groups, such as vertebrates (with a backbone) and invertebrates (without a backbone). They exhibit complex behaviors and social structures, and many species are vital to human life through companionship, labor, and ecological services.
