1. I am checking whether you too note as a practice grade (10 points). Also I am following the 80% practice rule for this next test. If you don’t have 80% on your practice work for this chapter, you cannot retake it nor make up any grade!

2.  Define ecology  Know the “levels of organization” in an ecosystem. ◦ Be able to provide an example of each NOT in the book  Be able to do a Quadrant Sampling seen in the quick lab on page 375 and Population and Samples on 377. ◦ We will do activity doing a practice quadrant sampling next week.

3.  Define biotic  Define abiotic ◦ Be able to identify biotic and abiotic factors when provided with a picture of an ecosystem  What is a keystone species? ◦ Why is the beaver a keystone species? (notice figure 2.2 on page 380)

4.  Define ◦ Producers ◦ Autotrophs ◦ Comsumers ◦ Heterotrophs  Where do producer get their energy since they don’t “eat” anything? ◦ What is the one example where producers do not need sunlight as an energy source?

5.  Define… ◦ Herbivores ◦ Carnivors ◦ Detritivores ◦ Decomposers  Know what primary, secondary, and teritiary consumers are  Be able to draw YOUR OWN food web similar to that on page 386. You will have to label the herbivores, carnivores, detritivores, decomposers, primary consumers, secondary consumers, and tertiary consumers.

6.  Be able to explain what the hydrologic cycle is. You may be asked to draw a visual.  Be able to explain what the oxygen cycle is. You may be asked to provide a visual.  Be able to explain what the carbon cycle is. You may be asked to provide a visual.  Nitrogen cycle: LEAVE ROOM IN YOUR NOTEBOOK, ½ of a page! I have a great demonstration for this and will be bringing in an aquaponics system that we will start. Aquaponics works because of the nitrogen cycle.

7.  I will give you a picture of a pyramid model and ask questions based on it. ◦ Lets do a practice question in class! I don’t think you guy will struggle with this concept.
