Unformatted text preview: RENR EXAM II REVIEW 1. Variety of organisms including Their unique attributes. Ex. a) b) c) 2. Most species are Abundant. 3. Biodiversity Towards the equator because of: a) b) c) d) e) f) 4. Range of conditions and Resources in which a species can survive and reproduce. 5. Range of conditions and Resources in which a species can survive with competitors and predators. 6. Entire group of species within A region 7. Restriction of species from a Regional pool in a local community is based on: 1) 2) 3) 8. Two species cannot occupy One niche (one will be Excluded) 9. Positive species response to The removal of competitors, Predators and disease. 10. Species diversity may vary In response to: 1) 2) 3) 11. Total number of species 12. Relative numerical distribution of species. 1. Biodiversity genetics adaptations special interactions 2. Moderately 3. Increases Time since perturbation Productivity Environmental heterogeneity Favorableness Niche Breadth Greater tropical land area 4. Fundamental niche 5. Realized niche 6. Species pool 7. Species sorting Tolerance of envir. Conditions Resource requirements of specie Interactions with competitors And preditors. 8. Competitive exclusion 9. Competitive release 10. Total niche in space of a Community. Niche overlap among species. Niche specialization among Species 11. Species richness 12. Species evenness 13. Weighted value of richness and Evenness (r x e) 14. Small Homogenous habitats (community) 15. All habitats in a region (alpha x beta) 16. Diversity difference between habitats within a region 17. Extinction is but its current rate is . 18. Rate of extinction is at its in Earths history. 19. Normal extinction process of ecosystems 20. Many species lost to catastrophes 21. Extinction associated with human activity. 22. Biodiversity has been supported on the basis of: a) b) c) d) 23. The study of processes affecting the maintenance, loss, and restoration of the Earth’s biodiversity. 24. Energy accumulated by autotrophs conversion of inorganic to organic energy. 25. Rate of energy accumulation 26. Total energy accumulation 27. Gross production minus respiration. 28. Weight of organic matter in an ecosystem. 29. Self-feeders that utilize inorganic energy sources....
