1. Food resources are rarely distributed uniformly in the environment. Most vary seasonally or have a patchy distribution and can become locally depleted. Give two possible responses of an animal species to depleted food resources in the real world. Explain how they work to solve the problem of limited prey and give an example of an animal species that employs each strategy.
2. As the polar ice shirinks with rising global temperatures, brown bears are expanding their range into the historical distribution of their close relative, the polar bear. Could this shift be explained by foraging strategy? If so, how?
