$500 Answer from Chapter 1 What is: Energy flows from the Sun to Earth and will then be released back into space

$100 Question from Chapter 2 Accelerating growth that produces a J-shaped curve when the population is graphed against time

$100 Answer from Chapter 2 What is exponential growth

$200 Question from Chapter 2 A factor that limits the growth, distribution, or amount of a population in an ecosystem

$200 Answer from Chapter 2 What is a limiting factor

$300 Question from Chapter 2 The size of a population that can be supported indefinitely by the available resources and services of an ecosystem

$300 Answer from Chapter 2 What is the carrying capacity?

$400 Question from Chapter 2 Maple trees are tall shade trees. How does this affect the ability of new maple seedlings to survive?

$400 Answer from Chapter 2 What is: shade from the mature trees prevents the growth of new seedlings

$500 Question from Chapter 2 This term describes the abiotic limiting factors and biotic relationships of a species in a given area

$500 Answer from Chapter 2 What is: ecological niche?

$100 Question from Chapter 3 The number and variety of life forms, including species, found within a specific region as well as all the number and variety of ecosystems within and beyond that region

$100 Answer from Chapter 3 What is biodiversity?

$200 Question from Chapter 3 A species that can greatly affect population numbers and the health of an ecosystem

$200 Answer from Chapter 3 What is a keystone species?

$300 Question from Chapter 3 Two different methods of measuring biodiversity

$300 Answer from Chapter 3 What is canopy fogging, quadrat sampling, transect sampling and netting

$400 Question from Chapter 3 The use of living organisms to clean up contaminated areas naturally

$400 Answer from Chapter 3 What is bioremediation?

$500 Question from Chapter 3 Water carried on a ship to help with stability; usually carries alien species

$500 Answer from Chapter 3 What is Ballast Water

$100 Question from Misc1 The biosphere includes: The lithosphere the atmosphere The hydrosphere All of the above

$100 Answer from Misc1 What is (d) : the living things form a layer over the entire planet

$200 Question from Misc1 True / False: Grasshoppers affect shrew populations by bottom-up population regulation

$200 Answer from Misc1 What is: TRUE

$300 Question from Misc1 True / False: Coral reef bleaching is the result of algae overgrowth

$300 Answer from Misc1 What is false: Algae loss

$400 Question from Misc1 Exponential growth cannot be sustained in nature because: Migration takes energy away from growth Hunting prevents growth of limiting factors that restrict growth The winter stops growth

$400 Answer from Misc1 What is c)

$500 Question from Misc1 How does this graph show that the hare population is regulated by the lynx population?

$500 Answer from Misc1 What is: The hare population shows the greatest variation; the lynx numbers never reach the high levels that are by the hare population; the hare population numbers are high, so there is a lot of food for the lynx population, so the hare population decreases and then so does the lynx population

$100 Question from Misc2. True or False: Biocontrol involves controlling invasive species

$100 Answer from Misc2. What is TRUE

$200 Question from Misc2. Logging in a forest: Allows new species to succeed Can destroy habitat for many species Can cause mass extinction Can lead to urban sprawl

$200 Answer from Misc2. What is: (b)

$300 Question from Misc2. When organisms die: Most carbon is released as carbon dioxide Nitrogen returns to the air Decomposers release carbon and nitrogen into the air Phosphate dissolves in water

$300 Answer from Misc2. What is (c) Cycling of matter requires the activity of decomposers

$400 Question from Misc2. The biotic members of an ecosystem can interact in 3 ways; this is one:

$400 Answer from Misc2. What is symbiosis, predation and competition

$500 Question from Misc2. Invasive species do these 2 things when introduced to a new area

$500 Answer from Misc2. What is: Take over the habitat Upset the equilibrium of an ecosystem

Final Jeopardy The graphs below represent the growth patterns to two different bacterial cultures over a period of time: Which graph shows only exponential growth? Which graph shows a growth pattern that is exponential only part of the time? Has either of these populations reached its carrying capacity? Explain A B

Final Jeopardy Answer What is: Graph A Graph B Graph B has reached it’s carrying capacity: The population size begins to taper off, showing that the particular area can not sustain a larger population (due to limiting factors) ie: the carrying capacity
