Consider the following questions:
1. Tell how ecosystem, ecotone, landscape, biome, and biosphere are different from one another.
2. Name and describe the roles of the three main types of organisms that make up the biotic structure of every ecosystem. Give examples of organisms from each category.
3. In terms of energy, why are there unlikely to be 6 or 7 trophic levels in a particular ecosystem?
4. Describe what differences in climate cause the Earth to be divided into each of the six major biomes.
5. What are limiting factors, zones of stress and ranges of tolerances? Give an example of each.
6. Explain how the energy of the sun is provided to a consumer such as a deer. Provide details that mention oxidation, respiration, photosynthesis, and heat.
7. How are ecological succession, climax ecosystem, primary succession and secondary succession different? Provide a clear, separate example for each. Why does succession occur?
8. Define and give examples of intraspecific and interspecific competition.
