1. Adaptations

2. Types of Adaptation Anything that helps an organism survive in its environment? Adaptations are inherited from their parents It also refers to the ability of living things to adjust to different conditions within their environments.? Structural adaptation Behavioral adaptations Physiological adaptations

3. Structural adaptations A structural adaptation involves some part of an organism's body. Teeth Body coverings Shells Quills Scales?? Camouflage Mimicry A structural adaptation involves some part of an animal's body, such as the size or shape of the teeth, the animal's body covering, or the way the animal moves.?? Teeth - since different animals eat different things, they don't all have the same kind of teeth Body coverings - Hair, scales, spines, and feathers grow from the skin.? All of these parts help animals survive in their environments.?? Movement - animals find food by moving from place to placeA structural adaptation involves some part of an animal's body, such as the size or shape of the teeth, the animal's body covering, or the way the animal moves.??

All of these parts help animals survive in their environments.?? Movement - animals find food by moving from place to place

4. Example of Adaptation The shape of an animal?s teeth is related to its diet. Herbivores, such as deer, have many molars for chewing tough grass and plants. Carnivores, such as lions, have sharp canines to kill and tear meat.

5. Camouflage Camouflage allows an animal to blend into its environment.? Makes it hard for enemies to single out individuals??

6. Mimicry Mimicry allows one animal to look, sound, or act like another animal to fool predators into thinking it is poisonous or dangerous.?? Coral snake (left) very poinsonous & Milk snake (right)Coral snake (left) very poinsonous & Milk snake (right)

7. Plant Adaptations Vascular-stems Root systems Thorns Leave type Broad:absorb more sunlight Small needle-like: reduce water loss Waxy: reduce water loss, protect from fire Poisonous/toxins

8. Behavioral adaptations Behavior adaptations include activities or behaviors that help an animal survive.? Innate Learned Survival Seasonal Behavior adaptations include activities that help an animal survive.? Behavior adaptations can be learned or instinctive. (a behavior an animal is born with). Social behavior - some animals live by themselves, while other live in groups.? Behavior for protection -? An animal's behavior sometimes helps to protect the animal.? For instance the opossum plays dead.? A rabbit freezes when it thinks it has been seen.? Behavior adaptations include activities that help an animal survive.? Behavior adaptations can be learned or instinctive. (a behavior an animal is born with). Social behavior - some animals live by themselves, while other live in groups.? Behavior for protection -? An animal's behavior sometimes helps to protect the animal.? For instance the opossum plays dead.? A rabbit freezes when it thinks it has been seen.?

9. Innate vs. Learned Innate Inherited through the genes Examples Flying for bees, birds Swimming for fish Walking for humans Speaking for humans Learned Learned from experience or from observing other animals Examples Type of language spoken for humans Riding a bicycle

10. Survival Behavior Finding food Predator-Prey adaptations Predator-animals that eat other animals Prey-animal being eaten Marking Territory Way that animals inform other animals that an area is occupied Defensive Action Protect resources, themselves, food, mates, offspring Courtship Behaviors used to find a mate Parenting Depend on parents for survival

11. Animal Defense Some animals use these methods of defense to protect themselves: Camouflage Snake Mimicry Mexican Milk Snake Bright colors Skunk and Poison Arrow Frog ?Hair? projections Hedgehog quills Deer Antlers

12. Seasonal Behavior Help organisms adapt to the environment Migration Hibernation Estivation Biological Clock

13. Migration Animals migrate for different reasons.? better climate better food safe place to live safe place to raise young go back to the place they were born. Adaptation that involves an animal or group of animals moving from one region to another and then back again.? Migration-is the behavioral adaptation that involves an animal or group of animals moving from one region to another and then back again.? Animals migrate for different reasons.? The reasons are as follows. better climate better food safe place to live safe place to raise young go back to the place they were born. Migration-is the behavioral adaptation that involves an animal or group of animals moving from one region to another and then back again.? Animals migrate for different reasons.? The reasons are as follows. better climate better food safe place to live safe place to raise young go back to the place they were born.

14. Hibernation Period of inactivity in which animal?s body temp., heart rate, and breathing rate slow down to conserve energy. Bats, woodchucks & bears. Hibernation- is a deep sleep in which an animal's body temperature drops to about the temperature of the environment.? Body activities, such as heartbeat and breathing are slowed causing the animal to need very little food.? Animals that hibernate are? bats? woodchucks snakes? bears. During the hibernation the animals live off of the fat that is stored in their body.?

15. Estivation Period of inactivity in the summer hot, dry places Snakes, lizards, frogs, toads

16. Biological Clock Internal control of animal?s natural cycle

17. Physiological Adaptations Behaviors controlled by the brain Reflexes Blinking Pain Swallowing Tolerance to a certain poison Logical thinking

18. Mammals warm-blooded All have some type of ?hair? Some are very specialized, such as white polar bear fur Care for young

19. Birds Leg Length Roseate Spoonbill (top right) Foot Webbing Laughing Gull (top left) Beak Shape Long Billed Curlew (bottom)

20. Reptiles cold- blooded Scales Some undergo hibernation and estivation Lay eggs on land Leg structure and position

21. Amphibians Cold-blooded Lay eggs in water Partially of fully webbed feet Have lungs or can absorb oxygen through their skin

23. Natural Selection and Population Changes Over Time

24. Natural Selection The process by which individuals are better adapted to their environment ?Survival of the Fittest? The fittest survive to pass on their traits to the next generation. Examples: Insecticide resistance Speciation Galapagos finches ??

26. Insecticide Resistance Speciation

27. Genetic Variation Differences that exist naturally among the members of a species Some traits are better suited than others to survive in their environment
