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.
