1 - $100 n 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? n Camouflage

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

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

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

1 - $500 n Bees and flowers are biotic or abiotic factors in an ecosystem. n Biotic

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

2 - $200 n The nonliving parts of an ecosystem are called what? n abiotic

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

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

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

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

3 - $200 n 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 n A shark’s powerful jaws

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

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

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

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

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

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

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

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

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

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

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

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

5 - $500 n n 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

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