Biosphere: a collection of ecosystems in a closed space
• P. 65: Draw a circle and label it “Me.” Then, draw five concentric circles and label each of them with the appropriate level of organization. Describe your population, community, etc.

• P. 67: In your own words, explain the difference between biotic and abiotic factors. Give three examples of each.
• The difference between biotic factors and abiotic factors is that biotic refers to living and abiotic refers to non-living. Examples of biotic factors include plants, animals, bacteria, and fungi. Examples of abiotic factors include sunlight, air temperature, and precipitation.

• 1a. Question: What are the six different major levels of organization, from smallest to largest, that ecologists commonly study?
• 1a. The six different major levels of organization are individual organism, population, community, ecosystem, biome, and biosphere.

• 1b. Question: Give an example of two objects or activities in your life that are interdependent. Explain your choice.
• 1b. An example of two activities in my life that are interdependent are cycling and my health. I need a healthy body to cycle and cycling helps maintain a healthy body.

• 3a. Question: Describe the three basic methods of ecological research.
• 3a. The three basic methods of ecological research are observing, which is using observations to answer questions about ecology; experimenting, which involves testing a hypothesis in a lab or natural setting; and modeling, which is the use of models, such as mathematical formulas, to answer questions about ecology.
A.Q. 1ab, 2a, 3ab, 4 on p. 68
• 3b. Question: Give an example of an ecological phenomenon that could be studied by modeling. Explain why modeling would be useful.
• 3b. Global warming is an ecological problem that could be studied by modeling more easily than by observation or experimentation because it occurs over a large area and a long period of time.
A.Q. 1ab, 2a, 3ab, 4 on p. 68
• 4. Question: Suppose you want to know if the water in a certain stream is safe to drink. Which ecological method(s) would you use in your investigation? Explain your reasoning and outline your procedure.
• 4. To determine if the water in a stream is safe to drink, I would conduct an experiment where 10 water samples are tested at 10 different locations in the stream…
