The following four graphs plot relationships between an x-variable and a y-variable. For each question, reference these graphs to decide on an answer that best addresses the question.  (a) Which of the above graphs represents the continuous logistic population growth model that we discussed in class, where the value for K is 5000? Remember to pay attention to all components of the graph, axis labels, values, and the value that you think represents K [ans1]. (b) Which of the following equations is most likely the equation for your answer above? [ans2] (c) In the above graphs, the population in panel b is likely more “r-selected” than the population in panel a. Which piece of evidence supports this claim? [ans3]

Your roommate is spinning the globe and says “Hey, I just noticed, it looks like there are rainforests at the same latitude in Africa as in South America. What a coincidence!” You congratulate your roommate for their keen observation skills and reply: Choose all the correct parts to include in your response: It’s colder at the equator because the sun hits at a more obtuse angle [ans1] Hot air readily absorbs moisture, then rises at the equator.  [ans2] As it increases in elevation, it decreases in pressure and then cools. [ans3] As this air cools, it dumps all of the moisture in the form of large amounts of precipitation. [ans4]
