In a previous lecture you learned about the tilt of the Earth of its axis and this tilt results in differential solar input depending on latitude. In this lecture you will learn how to calculate trophic energy transfer in KCal of energy/sq. meter/yr. On the next examination you will have a one-page problem in a similar format that is shown on this web site page. Be certain to practice these problems with your study group while this information is fresh in your mind.
Read page 727, 36.11 and study Figure 36.11 "An Energy Pyramid" in the textbook: Biology:Concepts & Connections.
Complete the crossword and questions for chapter 5. Have the crossword ready to hand in at the start of class.
Quiz each other on the terms listed on page 86 in the Survey of Biology Lecture Notes. Review the key points. It is a good idea to assign some of the key points to each member to review with the group. Practice the calculations; they represent an important problem on the next examination. The best way to do this as a group is to change the number of kilocalories at the start of the problem and have everyone recalculate the problem.
There are no specific references to trophic energy transfers on the CD ROM.
