Document Summary
Chapter 5 coping with environmental variation: energy. Know the 2/3 value for scaling between surface area and volume. Have some sense of what that exponent means means surface area increases less rapidly as mass, so if you plot those things with sa against volume, you would have a slope that is less than 1. Slide 2 autotrophs photosynthetic hetretrophs acquire energy by eating organic molecules produced byautotrophs, and autotrophs harness sun;s energy or inorganic chemicals to produce energy rich molecules, like sugar. Photosynthetic autotrophs use sun"s energy to run those reactions. Slide3 autotrophs: photosynthetic this species is a sea slug, and it incorporates algae from sea water into tissues, and uses those sugars that the organisms produce via photosynthesis. Sea slug is a heteretroph, and algae is autotroph, but in some cases, it may be considered an autotroph. Slug isn"t actually producing it"s own energy though. Slide 4 autotrophs: photosynthetic two main classes of biochemical reactions.
