5. This organism is at the top of the food chain shown. Food Webs - 100 What is the hawk/eagle? ===

6. Food Webs - 200 === What is a producer or autotroph? This is a word used to describe something that makes its own food.

7. Food Webs - 300 === What is level of complexity? (Chains show 1 connection, webs show all.) This explains why a food chain is different than a food web.

8. Food Webs - 400 === What is “There is not enough energy left to transfer up the food chain”? This is why food webs cannot go on forever.

9. Food Webs - 500 === This is the reason that arrows in a food web go from the food source to the consumer What is “the arrows follow the energy”?

10. Energy - 100 What happens to energy as you move up a food chain. What is “decrease”? ===

11. Energy - 200 === This is the type of energy generated by the sun. What is solar energy?

12. Energy - 300 === This is the type of energy transferred to a consumer eating food. What is chemical energy?

13. Energy - 400 === Is there more transferred to you when eating a pound of rice or a pound of meat? WHY?? What is rice? (Because less energy is lost through transfers up the food chain.)

14. Energy - 500 === This is how much energy gets transferred between each level of the food chain. What is 10%?

15. Interactions - 100 === These are 3 resources all consumers need to survive. What is food, water, and O 2 ?

16. Interactions - 200 === This graph is known as _________. What a J curve or exponential growth curve?

17. Interactions - 300 === In the lynx-hare lab, this is why did the lynx never grew out of control. What is “when their population grows, they would eat too many hares and run out of food”?

18. Interactions - 400 === This graph shows logistic growth. Explain why the graph levels off. What is there are limited resources?

19. Interactions - 500 === These are 2 reasons why the carrying capacity of a habitat could increase. What is: lack of predators, no disease, etc.?

20. Populations - 100 === This term means the number of organisms per unit area of space. What is population density?

21. Populations - 200 === Bad weather and drought are examples of density- _____________ factors. What is independent?

22. Population DAILY DOUBLE === This is what population distribution means. What is “where the organisms are within a habitat”?

23. Populations - 400 === These are 2 factors that could increase the population of an area. What is increased birthrate and immigration?

24. Populations - 500 === This is how a density-independent factor could impact a density dependent factor. What is (for example) a flood (DI) ruins crops and decreases food supply (DD)?
