Animalia

Animalia, commonly known as the animal kingdom, is one of the major groups of living organisms. It includes a vast diversity of creatures, ranging from simple forms like sponges to complex beings like mammals. Animals are multicellular, primarily heterotrophic organisms, which means they rely on consuming other organisms for food. They typically have specialized organs and systems, allowing them to move, respond to their environment, and reproduce. Unlike plants, most animals cannot produce their own food through photosynthesis. The animal kingdom plays a crucial role in ecosystems, contributing to the balance of nature and biodiversity.
