The Sonoran Desert is a unique biome defined by its high temperatures and low rainfall but also by the presence of giant cacti. Suppose a genetic study of a small, isolated population of desert tortoises revealed a new mutation that allows them to eat an otherwise poisonous cactus species that other tortoise populations cannot. Consider that this new cactus species is extremely abundant and nutritionally identical to other cacti, but its spines are so sharp that it takes an extraordinarily long time for the tortoise to process the food.A. Given the optimal foraging model you learned in class, how might the availability of this new food source affect the model terms s and h, compared to a tortoise without the mutation?B. Based on your answer for Part A, what is the key trade-off a tortoise with this mutation must consider? Use the logic of optimal foraging theory to predict the conditions under which this new foraging strategy would be advantageous for the tortoise's net energy gained (), and when it would not.

A new pollution control law has been passed b the state legislature requiring manufacturers to reduce pollution by 20%. A local industrialist manufactures copper, which results in the emission of three pollutants into the air: A, B, and C. under the state law the industrialist is required to reduce A by at least 50 units , B by at least 100 units, and C by at least 75 units. There are two pollution abatement methods available to the industrialist: (1) to use filters (x) or (2) to use cleansing additive for fuel (y). For each filter that is use, the emission of the three pollutants can be reduced by 1/2, 4/5, and 1 units respectively, for A, B, and C. For each ton of cleansing additive added to the fuel, the three pollutants can be reduced by 1, 5/2, and 1 unit, respectively, for A, B, and C. The cost of one filter is $500, and the cleansing additive costs $750 per ton. Based on this information, the industrialist's objective is to adopt the lowest-cost method of reducing pollution according to the law.
