1. Habitat & Adaptation

2. Habitat The environment in which a specific species lives in. Example : Canadian beavers live in the wetlands and lakes of North America.

3. Why are habitats important? Needed to meet other animals of the same species in order to reproduce Shelter Food and water To be in a climate to which they are adapted to

4. Adaptation? An adaptation is a way an animal's body helps it survive, or live, in its environment Species must be adapted to their habitat

5. Animals depend on their physical features to help them obtain food, keep safe, build homes, withstand weather, and attract mates. These physical features are called physical adaptations. They makes it possible for the animal to live in a particular place and in a particular way.

6. Each adaptation has been produced by evolution. This means that the adaptations have developed over many generations.

7. Examples of the basic adaptations that help creatures survive: shape of a bird's beak, the number of fingers, colour of the fur, the thickness or thinness of the fur, the shape of the nose or ears

8. What is a mimicry adaptation? Mimicry is adapting to look like something else. An example would be the hawkmoth as it looks just like a dead leaf, tattered and veined.

9. Example of Adaptations to Climate (p.225) Red fox vs. Arctic fox

10. PENGUINS! Penguins have webbed feet for powerful swimming. Their bodies are streamlined to reduce drag in water. Their wings, shaped like flippers, also help them "fly" underwater at speeds up to 15 mph. Penguins have to keep high body temperatures to remain active. They have thick skin and lots of fat (blubber) under their skin to keep warm in cold weather. They also huddle together with their friends to keep warm. Emperor penguins have developed a social behaviour that when it gets cold, they huddle together in groups that may comprise several thousand penguins. The dark coloured feathers of a penguin's back surface absorb heat from the sun, so helping them to warm up too.

11. Adaptation and movement Animal movement is adapted to specific habitats. (see p.226) Example: Smooth green snake: has no legs (it slithers)  lives in fields where plants provide shelter

12. Adaptation and eating Every animal species has physical adaptations that helps it eat. (see p.227)

13. Teeth and diet (see p.227) Canine teeth (tear)  carnivores Molars (grind, crush)  herbivores Incisor (shred, cut)  herbivores (bark) Premolar (grind, crush) Humans  all four types  omnivores

14. Beaks and diet Short, hooked, powerful  carnivorous (falcon) Short, wide base, powerful  herbivorous-granivorous (cardinal) Short and slender  Insectivorous – herbivorous (Tree swallow) Big, long, powerful  Omnivorous (Crow) Long and slender  Nectarivorous – invertivorous (humming bird)

15. Plants and adapting for food Plants will also adapt to their habitat in order to obtain food Example: Lichen : Algae and fungi live in symbiosis. The algae produces the food for the fungi and the fungi protects the algae from drought and temperature variations.

16. Adaptation and communication Communicating through visual signs : Fireflies (light) Communicating through Smells : skunks (spray) Communicating through Sound : dolphins (whistle)

17. Adapting through reproduction Flowering plants cannot move and so over millions of years they have adapted with the aid of insects that carry the pollen (Honey bees)
