Give an example of how a group of early Americans adapted to their environment, and one example of how a group changed their environment to fit their needs.

One example of a group of early Americans adapting to their environment is the Native American tribes of the Great Plains. These tribes were nomadic and followed the migration patterns of buffalo herds for their food source. They used every part of the buffalo for sustenance, clothing, and shelter, showing their resourcefulness in adapting to the harsh conditions of the prairie.

On the other hand, an example of a group changing their environment to fit their needs is the early American settlers in New England. These settlers cleared land for farming, built villages and towns, dammed rivers for irrigation and transportation, and significantly altered the landscape to create a more habitable environment for agriculture and settlement. This transformation had a lasting impact on the region's ecosystem and wildlife.
