1. 1.Mouths are quiet. 2.Begin the quick review section of your notes. 3.Raise your hand if you need something.

2. Quick Review 1. Process where chemical substances change into new substances = chemical reaction 2. Substances that are started out with before a reaction occurs = reactants 3. Substances that are ended with after a reaction occurs = products 4. A simplified explanation of a reaction using chemical symbols = chemical equation

3. Quick Review For the following use the chemical equation Br + NaO → NaBr + H 2 O 5. Reactants = Br and NaO and Products = NaBr and H 2 O 6. Does this obey the Law of Conservation of Mass = No, Hydrogen is products but not in the reactants.

4. Ecosystems and Adaptations Lesson 6.5 – Adaptations I

5. I can identify and explain beneficial adaptations for various biomes (desert, grassland, tundra, and coniferous forest). (3a) 1. Any characteristic that helps an organism survive in its environment = adaptation a. Three different types of adaptations: structural, behavioral, and physiological b. Structural: useful body structures or appearance

6. I can identify and explain beneficial adaptations for various biomes (desert, grassland, tundra, and coniferous forest). (3a) c. Behavioral: helpful behaviors that an organism automatically knows how to do when it is born. d. Physiological: body functions that help an organism to survive in its environment.

7. I can identify and explain beneficial adaptations for various biomes (desert, grassland, tundra, and coniferous forest). (3a) 2. Adaptations for Deserts a. Animals often have scales and are nocturnal (active at night ) to help them conserve water. Some have large ears that allows them to release excess heat. b. Plants have thick stems and perform a special version of photosynthesis called CAM photosynthesis that allows them conserve water.

8. I can identify and explain beneficial adaptations for various biomes (desert, grassland, tundra, and coniferous forest). (3a) 3. Adaptations for Grasslands a. Similar to deserts because of the low water and high temperature characteristics. b. Some plants can withstand or even need fires which commonly occur in grasslands. Animals have broad, flat teeth to chew plants.

9. I can identify and explain beneficial adaptations for various biomes (desert, grassland, tundra, and coniferous forest). (3a) 4. Adaptations for Tundra a. Fur and blubber (fat) keep organisms warm in this cold environment. b. Many animals migrate ( travel long distances) to warmer regions or hibernate (go completely inactive during winter). b. Plants are small and low to the ground with furry leaves. Dead leaves stay attached to the plant to help insulate it.

10. I can identify and explain beneficial adaptations for various biomes (desert, grassland, tundra, and coniferous forest). (3a) 5. Adaptations for Coniferous Forest ( Taiga ) a. Similar to tundra though larger plants and more animals are found. b. Trees have needles because they do not catch snow. c. The needles stay attached all year because they do not need to use energy and resources to regrow.

11. Guided Practice WORK WITH US…NOT AHEAD OF US!

12. I can identify and explain beneficial adaptations for various biomes (desert, grassland, tundra, and coniferous forest). (3a) 1. What physiological adaptation, not mentioned in class, does a conifer have? How does this help the tree? 2. Which organism has an adaptation that allows it to overcome the adaptations of the conifers?

13. I-N-D-E-P-E-N-D-E-N-T PRACTICE Do you know what that means?

14. Exit Ticket (5 Questions)

15. 1. A certain organism in the tundra changes its sleep patterns during the slightly warmer summer months. Which of these describes this change? A. Phenotypic alteration B. Structural adaptation C. Behavioral adaptation D. Physiological adaptation

16. 2. Walking through the woods in the middle of the winter, a hiker notices that most of the trees still have their leaves attached. Which biome is the hiker most likely walking through? A. Coniferous Forest B. Deciduous Forest C. Tundra D. Tropical Rainforest

17. 3. The picture at the right shows a Fennec fox, the smallest of the world’s foxes. In which biome is this organism most likely found? A. Tundra B. Coniferous Forest C. Grassland D. Desert

18. 4. The skull of an organism is shown at the right. Based on the shape of its teeth lack of fur, in which biome is this organism found? A. Tundra B. Coniferous Forest C. Grassland D. Desert

19. 5. Crassulacean acid metabolism (CAM) is a type of photosynthesis. A plant using CAM takes in carbon dioxide (CO 2 ) at nighttime, when it is cooler. The plant changes the CO 2 into an acid. During the daytime, the plant changes the acid into carbohydrates, without losing water to the warm air. In which environment are such plants best adapted for survival? A. Low-altitude, because the air pressure is greater closer to sea level B. Desert, because plants living in the desert have little water available C. High-altitude, because the night air is cooler in alpine zones of mountains D. Aquatic, because plants living in water need more carbohydrates to avoid drowning

20. 5. Which table shows adaptations that allow organisms to survive in a marshy wetland environment? A. B. C. D.
