3/20 Biology update and homework due 3/27
Hi folks, Today we continued to discuss relationships between organisms and we did a lab that modeled the complex relationship between the populations of predator and prey species. For homework this week: Read pages 366 -369 and pages 399 - 404 Do questions 1 - 6 on page 369 Do questions 1 - 7 on page 404 Also do the following: Predator-Prey lab conclusions Use the data from the included screen shots (they were the most representative of "real world" data) to make a 2 different graphs like the example I've included in this email. Each one of our trials represents one generation. Answer the following questions. 1. What type of relationship is presented by the graphed data. (Hint: it's the whole point of the lab.) 2. According to your graphs and the example, what eventually happens to the prey species when the predator species population increases? Why? 3. According to your graphs and the example, what eventually happens to the predator species when the ...
