Reading passage/section

Plants and animals have adaptations that help them survive. An adaptation is a body part or a behavior that helps a living thing meet its needs.

For example, some animals have spikes all around their body which are very spiny so that they protect themselves from enemies.

Wild animals have adaptations. Carnivores like tigers have sharp teeth for eating meat. Unlike carnivores, herbivores have flat teeth for eating plants.

Camouflage is another adaptation. Camouflage is the color or shape of an animal that makes it blend in with its environment. A chameleon can change the color of its body so that it cannot be seen easily.
