Classification of Animals

Prepared by: Christine Romero

* Animals cannot make their own food. They depend on other living organisms.

*Animals digest their food. They cannot use proteins, fats and carbohydrates directly.

*Many animals move from place to place. By moving around, they can find food, escape their enemies, find a better place to live and find mates.
