Adaptations in Animals

Advantages of adaptations

Getting a meal

Avoid becoming a meal

Keeping warm or cool

Raising offspring

Structural and Behavioral Adaptations

Structural adaptations are the special body parts of an organism that help it to survive in its natural habitat. For example the bill on a bird and the fur of a bear.

Behavioral adaptations are special ways an organism behaves to survive in its natural habitat. For example birds migration and hibernation are behavioral adaptations.

Assignment : Build a Beast

Use the following notes to help you complete (a) and (b) Environment: Hot and dry. Diet: Mainly spiky plants Movement: Non-flying animal

a) With the above information, imagine an animal that may or may not exist. Decide where it lives and what it eats. Think carefully the adaptations that it needs in order to survive in the habitat. Draw the animal that you have imagined

b) Describe in about 120 words, the characteristics and adaptation features of the animal that help it to survive in the habitat. You may refer to the drawing to help you. Complete it in nature study book.
