animal kingdom
The animal kingdom, scientifically known as Animalia, includes all living organisms that are multicellular and primarily heterotrophic, meaning they consume organic material for energy. Animals are characterized by their ability to move, respond to their environment, and reproduce sexually or asexually. They range from simple organisms like sponges to complex beings like humans. Animals are classified into various groups based on their traits, such as vertebrates (animals with backbones) and invertebrates (those without). This vast kingdom plays a crucial role in ecosystems, contributing to biodiversity and the balance of nature.
