Adaptation to environment.

1. Adaptationtoenvironment.

2. Adaptation to environment • Adaptation is the development of special characteristics by plants or animals to suit a particular environment.

3. Adaptation to environment Animals and plants evolve to suit their environment to increase their chance of survival.

4. Adaptation to environment • How are the following species adapted to their environment. Group work • Think about • the environment they live. • What features allow them to survive in that environment.

5. Adaptation to environment Environment – Extreme cold, snow and ice. Adaptations? Polar Bear

6. Adaptation to environment Environment – desert and arid (dry). Adaptations? Camel

7. Adaptation to environment Fish Environment – water Adaptations?

8. Adaptation to environment How are Flounders specially adapted to their environment. Environment – water. Adaptations?

9. Adaptation to environment How are Sharks specially adapted to their environment. Environment – water. Adaptations?

10. Adaptation to environment Cactus Environment – desert and arid (dry). Adaptations?

11. Adaptation to environment How are weeds specially adapted to their environment. Environment – Wet, pathways. Adaptations?

12. Adaptation to environment • Environment – Extreme cold, snow and ice. • Adaptations • Feed their young (better chance of survival) • Small ears (reduce heat loss) • Thick layer of fur (warmth) • White fur (camouflage) • Wide feet (for support on soft snow) • Sharp teeth (eat prey) Polar Bear

13. Adaptation to environment • Environment – desert and arid (dry). • Adaptations • Can survive up to 8 days without water. • Broad, soft feet (support on soft sand) • Humps contain fat (energy store) • Diet (thorny plants, seeds, dry leaves, bones) • Hair (short, thick and dense – protects skin from sunburn) • Long eyelashes (protect eyes from sand) Camel

14. Adaptation to environment Fish • Environment – water Adaptations • Gills (remove oxygen from water and release carbon dioxide from the blood) • Streamlined shape (reduces drag when swimming) • Mucus covered scales (reduces drag when swimming) • Large number eggs produced (increase survival as many eaten by predators.

15. Adaptation to environment How are Flounders specially adapted to their environment. • Environment – water. • Adaptations • Flat (aid ability to hide from predators) • Colour (camouflage)

16. Adaptation to environment How are Sharks specially adapted to their environment. • Environment – water. • Adaptations • Sharp teeth (to rip prey apart). • Can survive for a long time without food. • Smell blood from 5 miles away • Sense electrical activity from movement of fish

17. Adaptation to environment Cactus • Environment – desert and arid (dry). • Adaptations • Small leaves, spikes (to reduce water loss through transpiration). • Waxy cuticle on leaves (to reduce water loss through transpiration). • Extensive roots (to absorb water from deep underground).

18. Adaptation to environment How are weeds specially adapted to their environment. • Environment – Wet, pathways. • Adaptations • Strong roots (to prevent removal) • Flat leaves (to prevent removal)

24. Fossil Birds • Birds evolved from reptiles and share a number of their characteristics: • Elongate and mobile neck • Hollow pneumatic bones • Skull and neck joined by single occipital condyle • Inter-tarsal ankle joint • Epidermal scales
