How many seeds does it take to feed your mouse? So far, you've made it through the Great Plains, Yellowstone National Park, and you've just entered desert country. While the distinctive plant and animal communities of our three hot deserts typify the resilience and adaptability of life under harsh conditions, the plant and animal life of the mountains and river systems enrich the biological stew of the Basin and Range Province. A food chain always begins with plants, called producers. Energy is used by plants to grow and to reproduce. We often think of deserts as hot, dry places, but we often refer to them as extreme environments because while many are hot, many are cold as well.
