There is a special way to classify living things. This classification is called taxonomy. A man named Carolus Linnaeus created the classification system we use.

Living things are grouped or classified according to things they have in common, or ways that they are similar. For example, mammals all have hair and produce milk for their babies. Scientists use sets of rules to help them classify living things.

Each kingdom has different characteristics. Some of them make their own food, while others don't. Some of them lay eggs, while others have live babies. Some of them produce seeds, while others can't live without the other kingdoms.
