  1. Ecology Jeopardy Review!

  2. Terms-200 • This is the definition of a population.

  3. Answer: Terms 200 • What is a group of the same species in the same area? HOME

  4. Terms 400 • These are the living and non-living components of ecology

  5. Answer: Terms 400 • What are biotic and abiotic components? HOME

  6. Terms 600 • Ecology is the study of ___________________

  7. Answer: Terms 600 • What are interactions between organisms and their environment? HOME

  8. Terms 800 • This is the number of offspring in a female’s brood

  9. Answer: Terms 800 • What is fecundity? HOME

  10. Terms 1000 • Demography is the study of what?

  11. Answer: Terms 1000 • What is the study of populations and population processes? HOME

  12. Practice Problems 200 • Farmer Morris has 20 cows. In one year, 8 die, 4 are born and none immigrate or emigrate. What is the new population size?

  13. Answer Practice Problems: 200 • What is 16 cows? HOME

  14. Practice Problems 400 • Consider the following: a bee hive with 1257 members hatches 1580 new bees, in which 237 die and 30 bees leave to start a new hive. The new population size is _________

  15. Answer Practice Problems: 400 • What is 2570 bees? HOME

  16. Practice Problems 600 • Ken has 18 fish in his fish tank. 2 of his guppies have babies. The next day 3 fish die by eating themselves to death, and 4 of the guppy fry were eaten. The new population is 30 members. How many babies did the guppies have, counting the 4 that died?

  17. Answer Practice Problems: 600 • What is 19 fry/babies? HOME

  18. Practice Problems 800 • There is a school of 245 fish in the ocean. A pod of dolphins swims through and eats approximately 52 fish total. In the mayhem, 70 fish swim off and start a new school far away from the dolphins. Assuming there were no births, what is the new population of the fish?

  19. Answer Practice Problems: 800 • What is 123 fish? HOME

  20. Practice Problems 1000 • There is a population of 75 elephants in Africa. A group of poachers kill 41, and the populations split into 2 even populations as they panic and escape. In new population 1, 3 elephant calves are born. In new population 2, 5 are born, but one dies shortly after birth. What is the size of each population?

  21. Answer Practice Problems: 1000 • What is 20 elephants in population 1 and 21 elephants in population 2? HOME

  22. Population Dynamics and Limiting Factors 200 • These are the three factors that all populations have.

  23. Answer: Population Dynamics and Limiting Factors 200 • What is density, distribution and age structure? HOME

  24. Population Dynamics and Limiting Factors 400 • Humans fall on this type of survivorship curve.

  25. Answer: Population Dynamics and Limiting Factors 400 • What is a type I curve? HOME

  26. Population Dynamics and Limiting Factors 600 • These are the two types of population growth models.

  27. Answer: Population Dynamics and Limiting Factors 600 • What is exponential curve and logistic curve? HOME

  28. Population Dynamics and Limiting Factors 800 • What are the four types of age structures, and what is an example of each?

  29. Answer: Population Dynamics and Limiting Factors 800 What is rapid growth, slow growth, zero growth and negative growth? Rapid growth- Guatemala, Suadi Arabia, or Nigeria Slow growth- United States, Canada, or Australia Zero growth- Spain, Austria, or Belgium Negative growth- Germany, Bulgaria, or Sweden HOME

  30. Population Dynamics and Limiting Factors 1000 • This is the equation for estimating a population size at any point in time.

  31. Answer: Population Dynamics and Limiting Factors 1000 • What is “G= Initial Population + (B-D) + (I-E)”? HOME
