2. Example What is the University of Washington? A public institution in the Pacific Northwest with a Husky named “Dubs” as its mascot

3. List the following levels of organization in order of largest to smallest: biome, biosphere, community. Biosphere, biome, and community 100

4. 200 How is a community different from a population? Possible Answers 1.Communities include different species. 2.Communities usually occupy a larger area.

5. 300 How many different communities are featured in this pyramid? One

6. 400 Name all of the biomes we studied in class (one chance). Tundra, Grasslands, TDF, Rain Forest, Chaparral, Taiga, Desert

7. 500 Ecosystems are always in a balance. Explain 2 ways in which ecosystems are balanced. Possible Answers 1.Balance of predators and prey populations. 2.Balance of nutrients (C, N, O, and H) 3.Balance of energy (producers and consumers)

8. 100 In this food web, name the producer. Phytoplankton

9. 200 In this food web, which trophic level does the energy reach last? Tertiary Consumers

10. 300 In this food web, name ALL of the consumers and match them with correct trophic levels. P.C.: Grasshopper, Caterpillar, Chicken SC: Mynah, Chicken TC: Snake

11. 400 In this food web, the fox receives its carbon from which sources? Rabbits, Squirrels, Mice, Seed-Eating Birds, and Insectivorous Birds

12. 500 In this food web, which species can create its own food? Krill

13. 100 What trophic level does the hawk belong to? Quaternary Consumers

14. 200 If the producers gained 500,000 calories from the sun, how many calories will transfer to the secondary consumers? 5,000 calories

15. 300 Define the Rule of 10. The rule of 10 states that only approximately 10% of energy is transferred from one trophic level to the next.

16. 400 Energy is transferred from one trophic level to another in the form of this macromolecule. Carbohydrates store chemical energy in their chemical bonds.

17. 500 When an eagle eats a lizard containing 1,000 calories of energy, how many calories will the eagle receive from its meal? 100 calories

18. 100 This cycle is responsible for runoff and precipitation. Water cycle

19. 200 This process in the Carbon cycle releases carbon dioxide into the atmosphere. Respiration and combustion

20. 300 Producers play a role in all the cycles. Explain how producers plays a role in the carbon and water cycle. Carbon Cycle: Producers photosynthesize and make carbohydrates that store chemical energy for consumers. Water Cycle: Producers contribute to transpiration as water evaporates from them.

21. 400 A student drew this diagram of the carbon cycle. Explain 2 ways that this drawing is incorrect. 1.The “2” is in the wrong place. 2.There is no atmosphere.

22. 500 “Disrupting one cycle disrupts them all.” Explain how this statement could be true using specific knowledge of ALL cycles. Many possible answers.

23. 100 Define immigration. Individuals moving into a population.

24. 200 This type of population growth is seen when a population reaches its carrying capacity. Logistic Growth

25. 300 The carrying capacity of the rats in this graph is what? 3000 rats

26. 400 Give one reasonable explanation for why the population of Tigers in India decreased in 2007. Possible Answer (s): 1.Increased hunting/poaching. 2.Large emigration of tigers due to disease. 3.Natural predator increase.

27. 500 Exponential growth is possible under four (4) conditions. List them. 1.Zero predators 2.Unlimited resources 3.Unlimited space 4.Little disease

28. 100 Ice caps melting, migration of plants further away from the equator, and greater climate extremes is all evidence for what? Climate Change or Global Warming

29. 200 Deforestation is a serious concern to human beings. Using the carbon cycle, why is this true? Cutting down producers means cutting off the carbon supply we need as consumers.

30. 300 Throwing garbage and waste into the oceans disrupts many cycles and ecosystems. If too many whales eat garbage and die off, what would you expect to see in that ecosystem? The whales would not consume producers and the population of producers could increase. This could disrupt the ecosystem.

31. 400 Human populations have been able to grow exponentially since the industrial revolution. Why? 1.Better healthcare 2.Little competition for food. 3.No natural predators 4.Can live in almost any environment / any space.

32. 500 Explain how humans contributed to this graph. In 1947, humans started using DDT to spray producers so insects cannot eat them. As a result, the bald eagle population decreased.
