Transcription

1 Name: Class Period: Due Date: Unit 2.2 Test Review (What Gets You Moving?) Student Review TEKS on this test: 10B describe how biodiversity contributes to the sustainability of an ecosystem 10C observe, record, and describe the role of ecological succession such as in a microhabitat of a garden with weeds 8B analyze the effects of weathering, erosion, and deposition on the environment in ecoregions of Texas 8A predict and describe how different types of catastrophic events impact ecosystems such as floods, hurricanes, or tornadoes Answer the questions to the best of your ability. Use your class notes, links on the teacher s website and the textbook to help you. More study tips are at the end of this review. 1. Define biodiversity: 2. What 3 factors affect biodiversity? What are the threats to biodiversity? ( Hint: HIPPO) A. B. C. D. E. 4. Define sustainability:

2 5. Why is biodiversity important to ecosystems? a. b. c. 6. How does an ecosystem remain stable (sustainable)? 7. Make 3 claims about why one of the food webs above is less sustainable than the other. Support your claims with explanation as well as evidence from the food web. Ecosystem A Ecosystem B a. The links in in Ecosystem A vs. Ecosystem B: b. The consumers in Ecosystem A vs. B: c. Ecosystem A is more diverse which means it is more sustainable. Why?

3 8. Different environments can have different organisms that perform the same role (or have the same niche). Match these organisms and their environmental niche to a similarly niched organism from a different environment. Piney Woods beetle Edwards Plateau bird Trans Pecos bat Gulf Coast Prairies - lizard High Plains - ant Blackland Prairie toad 9. Circle the ecosystems that have great biological diversity Ocean coral reef California deserts Tropical rainforests Temperate rainforests Arctic Tundra Montane (Mountain) Habitats and Succession: 10. The process of is the series of predictable changes to the community that occur over time until a climax community is established. 11. What does the beginning of primary succession look like? 12. What does the beginning of secondary succession look like? 13. Which of the below leads to primary succession taking place in an ecosystem? (Circle all that apply) Volcanic eruption tornadoes hurricane forest fire retreating glacier 15. Which of the below leads to secondary succession taking place in an ecosystem? (Circle all that apply) Volcanic eruption over grazing hurricane forest fire retreating glacier 16. What types of events might change a microhabitat and cause primary succession to take place?

4 17. Succession is directional, different stages can be predicted, in order. What is the final level of the process of succession? 18. How do lichens contribute to primary succession? Weathering, Erosion, and Deposition: 19. Define weathering: 20. What is erosion? 21. What are the four agents of erosion? a. b. c. d. 22. What is deposition? 23. How do plants slow down erosion but can also contribute to weathering? Plants slow down erosion by Plants contribute to weathering of rocks by 24. What is the biggest single agent of erosion that shapes Earth s land surface?

5 25. Complete the table and explain the 5 types of mechanical weathering. Type of Mechanical Explanation Weathering Ice Wedging Exfoliation Root Pry Actions of Animals Abrasion

6 26. Explain the 5 types of chemical weathering. Type of Chemical Weathering Explanation Water (hydrolysis) Oxidation Carbonation (carbonic acid) Living Organisms Acid Rain (non-natural)

7 Texas Ecoregions and Weathering, Erosion and Deposition: 27. Which ecosystem in Texas would face the greatest damage due to potential erosion from hurricane? 28. How might a hurricane affect the Gulf Coast region of Texas and its ecosystem? 29. Carbonic acid is a weak acid produced when carbon dioxide combines with rainwater. Over long periods of time, water seeps through the ground and limestone exposed to this acid dissolves. Limestone rock layers are common throughout Texas. What is the most likely result of this process? 30. The rocks in Palo Duro Canyon can be reddish in color. They contain iron and other minerals. What process is responsible for making the rocks of the Palo Duro canyon red? 31. Water is the biggest agent of change on our planet. How does increasing the speed of water cause an increase of erosion? For questions Watch these videos on flash flooding: Desert flash flood: Flash Floods: Arizona flash flood: After the rain gathers in streams and begins to move more quickly, explain how this is an example of erosion.

8 33. Once the water has receded (left the area) what are the evidences that erosion and deposition have taken place? 34. How is the landscaped changed after the flash flood? What to study and studying tips: 1. A week before the test, starting going through the notes (both your own and the powerpoints posted on my website) and filling out this test review. 2. Highlight key words, especially scientific vocabulary know these terms!! 3. Make flashcards, make a quizlet, find some way to quick quiz yourself! 4. Look over warm ups posted online warm up questions are VERY similar to test questions. 5. Textbook sections to read: Biodiversity: p Ecological Succession: p Weathering, Erosion and Deposition: p Texas Ecoregions: p Utilize tools at your disposal: teacher website on the unit page, at the bottom, is the unit review section. Check out these videos and other links to help you understand topics you are weak in. 7. Above all ask questions when you do not understand the material! **If you lose this test review print another one from the teacher s website!
