2. An insect looks like a leaf, so it blends in with its surroundings and is hard for predators to see. What do we call this? Camouflage 1 - $100

3. 1 - $200 • Explain what type of symbiosis it is when a bacteria eats our dead skin cells, but it doesn’t cause disease. • Commensalism – we give the bacteria food, but we are not harmed

4. 1 - $300 • The series of changes that occur in an area where no ecosystem previously existed is called what? • Primary succession

5. 1 - $400 • Population size generally increases if the birth rate is greater than the death rate. True or False • True

6. 1 - $500 • Bees and flowers are biotic or abioticfactors in an ecosystem. • Biotic

7. 2 - $100 • An organism’s habitat must provide what for the organism to survive? • Food, water, shelter

8. 2 - $200 • The nonliving parts of an ecosystem are called what? • abiotic

9. 2 - $300 • To produce their own food, algae and plants use the abiotic factors sunlight, carbon dioxide, and what? • Water

10. 2 - $400 • There are 20 beetles in a garden. The garden is 5 square meters. What is the population density of the beetles? • 20 divided by 5 is equal to 4 beetles per square meter

11. 2 - $500 • An organism’s particular role in its habitat, or when and how it survives, is called its what? • Niche

12. 3 - $100 • What are the four limiting factors? • Food, climate, space, water

13. 3 - $200 • Which of the following is an example of a predator adaptation? a porcupine’s needles a shark’s powerful jaws a frog’s bright colors a plant’s poisonous chemicals • A shark’s powerful jaws

14. 3 - $300 • A hawk building its nest on an arm of a saguaro cactus is an example of Commensalism Parasitism Mutualism • Commensalism

15. 3 - $400 • A group of antelope leaving the herd in search of better grassland is an example of what? • Emigration

16. 3 - $500 • What is a host? • In a symbiotic relationship, its the organism that gives the second organism food and shelter.

17. 4 - $100 • Describe the levels of organization within an ecosystem. • Organism – single individual of a species • Species – organisms that can produce fertile offspring, and those offspring can produce fertile offspring • Population – a group of one species in a particular area • Community – groups of populations in a particular area

18. 4 - $200 • Both species benefit in the type of symbiosis. • Mutualism

19. 4 - $300 • The series of changes that occur in an area where no ecosystem previously existed is called what? • Primary succession

20. 4 - $400 • Population size generally decreases if the birth rate is greater / less than the death rate. • Less

21. 4 - $500 • Explain what carrying capacity is. • The total amount of organisms an area can support.

22. 5 - $100 • Explain the difference between a population and a community. • Population consists of one species in an area. • Community consists of all of the populations in an area.

23. 5 - $200 • What is the smallest unit of organization in the picture? Give one example • Organism

24. 5 - $300 • Explain why secondary succession usually occurs more rapidly than primary succession. • Soil and organisms are already there to start the succession.

25. 5 - $400 • Explain what type of symbiosis it is when a live bacteria lives inside a human’s intestine and makes vitamin K. • Mutualism – the bacteria makes vitamin K for us and we give the bacteria a home

26. 5 - $500 • Explain what type of symbiosis it is when a mosquito bites us. • Parasitism – the mosquito takes our blood and we are injected with the mosquito’s saliva which we are allergic to

27. Final Jeopardy • Give an explanation for the pheasant population at points B, C, and D. • B – met carrying capacity • C – died from not enough food, predators, or immigrated • D – starting to come back but still may be dealing with what caused the decrease at C
