1 - $100 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 - $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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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.

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

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

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

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

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
