Biological Diversity, Animal Behavior & Endangered Species Study Guide 1. What is biodiversity? What is the underlying cause of biodiversity? 2. Biological diversity involves the following concepts. Explain each: Genetic diversity Habitat/ecosystem diversity Species diversity 3. Why is biodiversity high in some places but low in others? 4. List 3 ways diversity is important. 5. What is the only reason why things are becoming extinct at such a fast rate? 6. What are the characteristics of an endangered species? 7. Explain in situ vs ex situ. 8. List 3 endangered species. 9. Summarize the Endangered Species Act. 10. How do scientists account for the development of life on earth? 11. What is biological evolution by natural selection, and how can it account for the current diversity of organisms on the earth? 12. How can geologic processes, climate change and catastrophes affect biological evolution? 13. What is an ecological niche, and how does it help a population adapt to changing the environmental conditions? 14. How do extinction of species and formation of new species affect biodiversity? 15.
