Tall grass prairies are located between the Mississippi River and Nebraska. They receive between 10 to 30 inches of rain per year and have a growing season from late spring to early fall when temperatures are between 50 to 70 degrees Fahrenheit. The soil is dark brown or black and nutrient-rich due to the dense roots of the grasses. Native plants such as sunflowers, asters, and wildflowers have adaptations like deep roots and upright forms to compete for sunlight and water in the prairie environment. Animals such as bison, deer and rabbits also have adaptations like burrowing, traveling in herds, and thick winter coats. However, human impacts such as farming non-native plants have reduced tallgrass prairies
