Prairies are vast, flat grasslands characterized by few trees and a rich variety of grasses. They are typically found in regions with moderate rainfall, which supports the growth of these plants. Prairies play a crucial role in the ecosystem, providing habitat for many species of wildlife, including birds, insects, and mammals. These grasslands are often divided into three types: tallgrass prairies, mixed-grass prairies, and shortgrass prairies, each varying in the height and type of grasses present. Prairies are important for agriculture, as they are often converted into farmland for crops like wheat and corn.
