E N D
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.
Ostrich Hummingbird Adaptations in birds
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
Adaptations • A characteristic, structure, or behavior that helps an organism live.
Adaptations also helps organisms to: • get food • protect themselves • move • reproduce, • carry on life processes.
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
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
Adaptations • The emperor penguin, for example, has adaptations that help it live successfully in an extremely cold climate. *** Reference 12
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
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.
Diversity of Adaptations • The long, broad wings of a turkey vulture help it glide and soar without using large amounts of energy
Diversity of Adaptations • Jackrabbits living in the desert have long ears that provide a large body surface for giving off extra heat.
Patterns of Adaptations Similar adaptations occur in organisms for two main reasons
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
Dolphin Shark Organisms in similar habitat
Sea Turtle Pond Turtle Organisms in similar habitat
Related organisms • Organisms may have similar adaptations because they are related to each other.
Large groups of organisms have the same general adaptions. • Example: • All plants have cell walls • most have chlorophyll (to capture energy from the sunlight)..
All birds have wings and use their beaks to get food, • All fish have gills and fins.
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
Species • All the members of a species have some adaptations that distinguish them from other species.
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.
Species • . Consequently, pandas are not the same species as bears, even though they look a lot alike.*** Reference 23
Indian Elephant African Elephant Members of one species may resemble those of another species. *** Reference 17
