Instructions: Answer EITHER Option A OR Option B in the space provided. NOTE: answers to questions can be provided in point form/bullet point. Option A: A conservation biologist is monitoring a population of white-tailed deer in an Ontario provincial park. Over a five-year period, the population hits its carrying capacity, leading to a shortage of food resources and an increase in the transmission of a parasitic disease. In the sixth year, a severe early winter blizzard hits the park, causing a sudden spike in mortality. In point form, compare and contrast the two types of limiting factors affecting this deer population. Your response must identify which specific events in the scenario represent density-dependent factors and which represent density-independent factors, and explain how each factor operates to regulate population size. Option B: A team of ecologists introduces a small group of ring-necked pheasants onto an island with abundant food resources and no natural predators. Initially, the population growth follows a J-shaped curve. However, after several generations, the growth rate begins to slow down as the population size nears the island’s carrying capacity, transitioning the growth into an S-shaped curve. In point form, compare and contrast the two mathematical models of population growth illustrated in this scenario. Your response must identify each growth model by name, describe the specific environmental conditions that produce each distinct curve shape, and explain the biological significance of carrying capacity (K) in the transition between them.

After September 11, 2001, the United States used waterboarding on non-American prisoners, sent prisoners to other countries for torture through a process called rendition, conducted drone strikes without a legislative framework, and expanded mass surveillance. According to Smallman and Brown, why do these actions matter for how we think about security?
