Biology Semester 2 Final Study Guide 2012
Ch. 13.
1. Define population
- Consists of all the individuals of a species that live in a specific geographical area and can interbreed.
2. Define natural selection.
- The differential rate of reproduction.
3. Explain how gradualism and punctuated equilibrium relate to evolution.
- Both involve the species evolving either over a long period of time or rapidly.
4. What does a paleontologist do?
- Scientists who study fossils.
Ch. 14.
5. Define binomial nomenclature.
- Linnaeus’s two-word system for naming organisms.
6. Define taxonomy.
- The science of naming and classifying organisms.
7. The basic (smallest) biological unit in the Linnaean system of classification is the Species.
8. What is an advantage of our scientific naming system?
- It’s more specific and descriptive.
Ch. 16.
9. Define community.
- The many different species that live together in a habitat.
10. Define habitat.
- The place where a particular population of a species lives.
11. Ecology is the study of the interactions of living organisms with one another.
12. What does an ecosystem consist of?
- A community and all the physical aspects of its habitat.
13. Compare examples of abiotic and biotic factors.
- Abiotic is the physical aspects of a habitat and biotic is the organisms in a habitat.
14. Define succession.
- A somewhat regular progression of species replacement.
15. When an organism dies, what will most likely happen to the nutrients in its body?
- The nutrients are released back into the environment to be recycled by other organisms.
16. Fungi are decomposers in a food web.
17. Why are food webs more commonplace than food chains?
- In most ecosystems, energy does not flow in straight paths.
18. Give examples of fossil fuels.
- Coal, oil, and natural gases.
Ch. 17.
19. Give an example of commensalism.
