Study Guide Lectures 6-9, October 12, 2008 BIS2B Fall 2008 Dear Class: This edition of our study guides will bring us up to date as we approach the first midterm. We have established some principles that you should follow in your preparations for this midterm. 1. Attend all lectures and review the lecture material afterwards. 2. Form a study group and spend part of your time going over material with classmates. Let every one talk, listen to every one. You cannot fail to benefit from discussions about the material with classmates. 3. Find each point from the lecture in the reading in the text and in the supplementary reading. Repeating, focus on the reading that applies to the specific points and their relationships to one another in the lectures. 4. Use the study guides and the clicker questions as an indication of the sorts of questions that you will see on the examinations. You will note that I am tending to be less specific in this study guide than in the first ones. You should be able to insert the greater specificity that we developed in the first guides into these later ones. Lectures 1-5. The study guides that you have from lectures 1-3 are detailed very useful for the learning the material. Lecture 6 concerned the origins of soil and plant nutrients, some important factors of healthy soil that will support GPP. You should be able to answer such questions as ______________________(a, b, c) are major physical (chemical, biological ) factors in soil genesis. This kind of question follows directly from the lecture and reading. We discussed at some length in this and in following lectures the ways that different soils can respond to human activities and the unfortunate results of these activities and responses. You should know the details of the examples that we discussed, be able to describe the biology, chemistry, and physics of these examples to the degree that we covered them in lectures. Finally, you should be able to describe the costs to humans of these soil responses to human activities. You definitely need to know the carbonic acid reaction (CAR), the names and formulas of its component parts, and where it is important in nature. We have highlighted this reaction in multiple lectures. 1

Q. Name three topics (1, 2, & 3 a) to which we have found this reaction pertinent, 1a.___________________________ 1b. _______________________ 2a. ___________________________ 2b. _______________________ 3 a. ___________________________3.b_________________________ In 1, 2, & 3b describe the activity and relationships in which CAR participates. We addressed CAR a couple in this lecture, and 3 in lecture 9 on Friday. With a discussion of the figure from our text, we discussed the important relationship between root metabolism, soil chemistry, and nutrient supply in the soil solution. You should write a series of questions about this relationship and be able to diagram it, explaining its dynamics. If you saw the diagram 36.6 without labels, you should be able to label it and fill in the reactions.

What students are saying

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
