$100 Question: CC Graph 1 When did the rabbits reach their carrying capacity?

$100 Answer: CC Graph 1 End of June/August 1

$200 Question: CC Graph 1 What is the carrying capacity of rabbits here?

$200 Answer: CC Graph 1 About 65 rabbits

$300 Question: CC Graph 1 Why does the rabbit population increase in the highlighted region?

$300 Answer: CC Graph 1 Population below carrying capacity (more than enough resources for everyone)

$400 Question: CC Graph 1 If there is a fire that destroys all the grass in August, what will happen to rabbit population size? Why?

$400 Answer: CC Graph 1 Decrease: not enough food for everyone/death rates exceed birth rates

$500 Question: CC Graph 1 Identify 2 months where birth rate exceeds death rate

$500 Answer: CC Graph 1 May, June, July

$100 Question: CC Graph 2 What are three factors that limit deer population size?

$100 Answer: CC Graph 2 Food (grass), water, oxygen, free space

$200 Question: CC Graph 2 Why does population size decrease in the highlighted portion of the graph?

$200 Answer: CC Graph 2 Population size above carrying capacity: not enough resources to go around/death rate exceeds birth rate

$300 Question: CC Graph 2 Draw this graph, and circle where birth rate exceeds death rate by the most

$300 Answer: CC Graph 2

$400 Question: CC Graph 2 What is the carrying capacity of deer here?

$400 Answer: CC Graph 2 Approximately 80

$500 Question: CC Graph 2 Draw this graph, and circle the point at which deer exceed carrying capacity

$500 Answer: CC Graph 2

$100 Question: CC Graph 3 In what three years does population size most exceed carrying capacity?

$100 Answer: CC Graph 3 Around 1850, 1875, 1906

$200 Question: CC Graph 3 Why does the population decrease in the highlighted section?

$200 Answer: CC Graph 3 Population size above carrying capacity: not enough resources to go around/death rate exceeds birth rate

$300 Question: CC Graph 3 Why does population size rise again after each big drop?

$300 Answer: CC Graph 3 It falls below carrying capacity, so there are enough resources again/birth rates exceed death rates

$400 Question: CC Graph 3 Identify three periods of time where birth rate exceeds death rate

$400 Answer: CC Graph 3

$500 Question: CC Graph 3 What is the relationship between population size and carrying capacity between ?

$500 Answer: CC Graph 3 Population size is equal to carrying capacity (both increase at the same rate)

$100 Question: Lagniappe “The maximum number of organisms that can live somewhere based on limiting factors”

$100 Answer: Lagniappe Carrying capacity

$200 Question: Lagniappe What impact does available food, water, free space have on an ecosystem?

$200 Answer: Lagniappe They act as limiting factors, and determine how many organisms can live in that ecosystem

$300 Question: Lagniappe Which of the following is NOT a limiting factor: water, evaporation, oxygen, minerals, sunlight

$300 Answer: Lagniappe Evaporation! It is not a resource that determines how many organisms can live somewhere. (Rainfall, which is related to evaporation, is a limiting factor. But rainfall and evaporation aren’t the same thing.)

$400 Question: Lagniappe Lions hunt and eat wildebeest. If a hunter enters the grassland and kills all the lions there, what will happen to wildebeest population size? WHY?

$400 Answer: Lagniappe Population size will increase, because birth rates will exceed death rates/carrying capacity will increase

$500 Question: Lagniappe Bald eagles eat vertebrate fish. If humans pollute the water and many fish die, what will happen to bald eagle population size? WHY?

$500 Answer: Lagniappe Population size will decrease, because death rates will exceed birth rates/carrying capacity decreases

$100 Question: Lagniappe What is carrying capacity?

$100 Answer: Lagniappe Maximum number of organisms that can live somewhere, based on limiting factors

$200 Question: Lagniappe What are three limiting factors?

$200 Answer: Lagniappe Food, water, free space, oxygen, minerals

$300 Question: Lagniappe If more organisms are being born than are dying, what will happen to population size?

$300 Answer: Lagniappe Population size will increase

$400 Question: Lagniappe If a population has exceeded its carrying capacity, what will happen to it? Why?

$400 Answer: Lagniappe Population size will decrease, because there won’t be enough resources for all organisms. So more organisms will die than are being born.

$500 Question: Lagniappe Bears eat salmon. If a disease causes massive amounts of salmon to die, what will likely happen to the bears? Why?

$500 Answer: Lagniappe Bear population size will decrease, because there is not enough food (salmon) to support all the bears. So death rate will exceed birth rate.

Final Jeopardy Fill in the blank: reducing _____ makes ecosystems _____ stable. Provide one example that proves why this is true.

Final Jeopardy Answer Reducing biodiversity makes ecosystems less stable. Cut down all the trees in the rainforest  everything that needs those trees (for food, shelter, etc.) dies  everything that needs those organisms dies  everything dies
