Diversity and Adaptation

1. Diversity and Adaptation

2. Objectives • Define and explain the term adaptation. • Explain why different organisms living in the same habitat may have similar adaptations. • Infer how organisms use their senses to adapt to their environment.

3. What makes organisms different from each other?

4. Adaptations

5. Ostrich Hummingbird Adaptations in birds

6. The hummingbird's wings, allow it to hover at a flower while it sucks nectar with its long, narrow beak. *** The powerful front legs and long tongue of the anteater helps it get into the hard termite mounds. *** Reference 6 Examples of adaptations

7. Adaptations • A characteristic, structure, or behavior that helps an organism live.

8. Adaptations also helps organisms to: • get food • protect themselves • move • reproduce, • carry on life processes.

9. Examples of adaptations • The sharp teeth and claws of a tiger – for catching and eating prey. • A chameleon's long, sticky tongue - for catching insects***. • The joints of your legs - for walking. Reference 14

10. Adaptations • An organism's adaptations help it survive in a particular habitat. • A habitat is the area or place where an organism lives.*** • With its adaptations, an organism is adapted to its habitat. Reference 5

11. Adaptations • The emperor penguin, for example, has adaptations that help it live successfully in an extremely cold climate. *** Reference 12

12. Diversity of Adaptations

13. Diversity of Adaptations • As you may know, many different habitats exist on the earth. • Each habitat has a variety of organisms that live there in different ways. • This variety of life is called diversity. *** Reference 13

14. Diversity of Adaptations • Coconuts, which are the seeds of one kind of palm tree, can float from island to island because of their thick, airy husks.

15. Diversity of Adaptations • The long, broad wings of a turkey vulture help it glide and soar without using large amounts of energy

16. Diversity of Adaptations • Jackrabbits living in the desert have long ears that provide a large body surface for giving off extra heat.

17. Patterns of Adaptations Similar adaptations occur in organisms for two main reasons

18. Organisms in the same habitat • Because they are in the same environment, organisms need similar adaptations. • Two plants living in a dry habitat may have small, thick leaves in order to survive the harsh environment..*** Reference 16

19. Dolphin Shark Organisms in similar habitat

20. Sea Turtle Pond Turtle Organisms in similar habitat

21. Related organisms • Organisms may have similar adaptations because they are related to each other.

22. Large groups of organisms have the same general adaptions. • Example: • All plants have cell walls • most have chlorophyll (to capture energy from the sunlight)..

23. All birds have wings and use their beaks to get food, • All fish have gills and fins.

24. Species

25. Species • Living things that share a large number of characteristics and adaptations may be placed in a group called a species. A species is made up of organisms that look similar and can mate with each other to produce offspring that can reproduce.*** Reference 1

26. Species • All the members of a species have some adaptations that distinguish them from other species.

27. Species • For example, the panda has a sixth finger for stripping leaves from bamboo stems. This special finger developed from a wristbone. It is an adaptation that is not shared by any other animal.

28. Species • . Consequently, pandas are not the same species as bears, even though they look a lot alike.*** Reference 23

29. Indian Elephant African Elephant Members of one species may resemble those of another species. *** Reference 17
