A characteristic that helps an organism survive in its environment Living things have bodies that are adapted for the places they live and the things they do. » Structural adaptation » Behavioral adaptation ˃ Teeth shape ˃ Migration ˃ Beak/bill shape ˃ Hibernation ˃ Body coverings (fur, scales, spines, coloration) ˃ Movement (long legs for running, wings for flying, fins for swimming) ˃ Hiding ˃ Social or isolated 4 physical features of an organism to help it survive in its environment. The way the body is made or works » Grinding teeth in herbivores » Webbed feet for swimming » Needle leaves in cactus » Gills in fish » Hollow bones in birds » A bulb in plants How do these structural adaptations help an organism survive? When we learned about the human skeletal system, we learned that our bones are responsible for several jobs in our bodies: » Provide Shape and Support » Protect Organs » Making blood cells » Storage » Birds have hollow bones… why? Hard on the outside with air cavities inside Lighter weight Hollow bones look like other bones from the outside, with the usual hard exterior you'd expect a bone to have. But instead of being filled with marrow as your bones are, a hollow bone has an air cavity inside. The hollow part of a bird bone isn't wasted space. In some bones, the hollow cavities contain extensions of the air sacs from the lungs. These air sacs help the bird to get the oxygen it needs to fly quickly and easily. Penguins cannot fly. Do you think their bones are hollow? Why or why not? Penguins bodies are adapted for movement through water. They spend up to 75% of their lives in the sea. Having solid dense bones helps penguins stay underwater and resist floating to the top. » Can you find the animals in the pictures? https://www.youtube.com/watch?v=0uE2XMXZUQY https://www.youtube.com/watch?v=XpdoDBYuHIA » Mimicry allows one animal to look, sound, or act like another animal to fool predators into thinking it is poisonous or dangerous. milk snake Venomous coral snake » Many animals’ only line of defense is their colors. » The warning colors of red, yellow, orange, and bright blue warn others that these animals might be dangerous and should be avoided! » Migration » Hibernation » Dormancy in plants 27 » Behavioral adaptations include activities that help an organism survive. » Behavior adaptations can be learned or instinctive. » Living together in groups » Solitary » Social behavior is all about how an animal interacts with members of its own species. For instance, does it live in a colony or on its own, does it fight to be top of the pecking order, or does it try to keep strangers away from its home? » Bird calls » Frog croaking » Cricket chirping a group of animals moving from one region to another and then back again. 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. This is deep sleep in which animal’s body temp drops, body activity (metabolism) are slowed way down to conserve energy. E.g. bats, squirrels & bears.
