Chapter 2 Principles of Ecology Expectations
By the end of the unit you should have the following completed:
1. Be able to define and give an example when appropriate of:
Group A: Ecology, biosphere, abiotic factors, biotic factors, population, community, ecosystem, habitat, niche
Group B: autotroph, heterotroph, scavenger, decomposer, food chain, food web, herbivore, carnivore, omnivore
2. All assigned reading should be read with the goal of being able to discuss/explain the information contained in them.
Section 2.1 Organisms and their Environment
Section 2.2 Nutrition and Energy Flow p.48-54
3. Class notes should recorded and committed to memory.
4. Have the following expectation questions answered in a complete sentence on a separate piece of paper:
Group 1 questions (Section 2.1)
1. List 2 different biotic and abiotic factors in a river ecosystem.
2. Describe the levels of organization of an organism that lives in your biome.
3. List at least 2 populations that share your community.
4. Differentiate between the niche and the habitat that is found in your community.
5. Clownfish are small, tropical marine fish usually found swimming among the stinging tentacles of sea anemones. The clownfish is protected by the sea anemone but the sea anemone does not benefit from the clownfish. What type of symbiotic relationship do these animals have? Give a reason for your answer.
Group 2 questions (Section 2.2)
1. Describe a food chain that is contained in the reading for this chapter. Be sure to include at least 4 links in your chain.
2. Compare (similarities) and contrast (differences) autotrophs and heterotrophs?
3. Why do autotrophs always occupy the lowest level of ecological pyramids?
4. Evaluate the impact on living organisms if the Sun began to produce less energy and then finally burned out.
Group 3 questions (Section 2.3)
1. List 4 important biogeochemical processes that cycle nutrients.
2. Differentiate between
3 processes that occur in the water cycle?
3. Explain the importance of nutrient cycling to an organism of your choice.
4. How does carbon move from the abiotic to the biotic parts of an ecosystem
5.The following labs should be completed:
Food Chain Rummy |
Minilab 2.1 p. 38 |

Biotic and Abiotic Factors observation |

Extra Credit: Students eligible for this extra credit have all of their assigned work turned in/checked on time for the chapter. This assignment must be passed in before the test is taken (maximum 3 pts on test)
Activity 1: Find the names of five organisms that belong to a tide pool community on the coast of Maine. Choose 5 organisms that have some relationship to each other. Explain how they interact/affect each other. Research some abiotic factors that limit or affect the organisms. Write a report on your research. The report must be typed
Activity 2: Do the online review test which you can access at by clicking the link below.

When you complete the test, your results will be sent to me and you will be told which you got wrong. You can only take the test once for extra credit. If you get 80 or better on the test you will get 2 pts on your first ecology test.
