3. Population I Name one way a population can grow. More births than deaths; immigration

4. Population I: 200 Provide two examples of a limiting factor Predation, disease, natural disaster, deforestation, etc.

5. Population I: 300 Which of the following letters would most likely represent exponential growth? J or S “J”

6. Population I: 400 What is meant by carrying capacity? The maximum number of individuals that an environment can support

7. Population I: 500 Explain exponential growth. Exponential growth refers to growth of a population at a constant rate; only under ideal conditions

8. Population II: 100 Name and spell the term used to describe the movement of individuals into an area. Immigration

9. Population II: 200 There are 20 white-tailed deer occupying a forest of 10 square miles. What is the population density of the deer? 2 deer per square mile

10. Population II: 300 Explain how a population would achieve a negative growth rate More deaths than births

11. Population II: 400 List and describe the three types of geographic distribution 1.Random- no order 2.Clumped- grouped 3.Uniform- orderly; a pattern; evenly dispersed

12. Population II: 500 Is disease density-dependent or independent? Why? Density-dependent; disease will only become limiting when the population is large and dense

13. Succession: 100 Primary Succession occurs when this abiotic factor is missing. SOIL

14. Succession: 200 Name two events that may initiate the process of secondary succession. Natural Disaster; deforestation

15. Succession: 300 What is significant of the presence of a climax community? Climax communities are a stable group of plants and animals in an area; function optimally until disturbance

16. Succession: 400 Explain the process in which a pioneer species, like lichen, creates soil. Lichen adheres to the surface of rock, and begins creating cracks (via the release of acid from photosynthesis); rocks are broken down, creating soil; death and decay of lichen add nutrients to soil

17. Succession: 500 Explain how larger, complex plant species come to existence in an area undergoing ecological succession. As pioneer species die and decompose, the soil is enriched, allowing for other plants with the necessary adaptations to grow and develop; they too die and decay further enriching the soil with nutrients- new plants with the necessary adaptations are able to move into the area, grow and develop

18. Biodiversity: 100 The word used to describe the genetic variability of living organisms Biodiversity

19. Biodiversity: 200 What is an endangered species? A group of organisms near extinction

20. Biodiversity: 300 Name and describe one effort to protect the Earth’s biodiversity. National Parks-preservation of habitat and living organisms Captive Breeding- breeding of endangered species held in captivity; held until population grows and begins to stabilize; released into natural environment

21. Biodiversity: 400 Category 4 – 40 Points Name and describe one way humans interfere with biodiversity 1.Hunting: Death of too many animals limits those genetically viable organisms which can reproduce 2.Deforestation: Loss of habitat/resources may lead to death of organisms; loss of genetic variability in gene pool

22. Biodiversity: 500 Explain the significance of the Earth’s biodiversity. More biodiversity means the possibility of more medicine; loss of other resources

23. Miscellaneous: 100 The name used to describe those factors that cause a decrease in the size of a population. Limiting Factors

24. Miscellaneous: 200 Logistic growth can only occur following a period of this type of growth. Exponential

25. Miscellaneous: 300 Name two events that would initiate primary succession. Volcanic eruption; Glacial retreat (both exposing bare rock)

26. Miscellaneous: 400 Describe what is meant by a density-independent limiting factor. Provide an example. These factors are limiting to the population regardless of its size; weather cycles, natural disasters, human interference

27. Miscellaneous: 500 Would the introduction of a parasite become limiting to a small, highly scattered population? Why or why not? No…parasitism is a density- dependent LF; in order to become limiting the population would need to be large and dense

28. Final Jeopardy “The Lonliest Animals” What was the significance of the gate (within the pond) that separated the male and female rafetus turtles?
