how did native americans adapt to their environments
This question is FAR too broad. There were many, many groups of people (and therefore civilizations) that developed in what we now call North America.
You'll need to decide on one or two groups to concentrate on or narrow down the question.

You cannot say "civilization" (singular). There were many, many groups of people.

To answer your question about how Native Americans adapted to their environments, it is important to note that different Native American tribes and civilizations had distinct ways of adapting to their specific environments. Their adaptations were based on factors such as climate, geography, available resources, and cultural practices.
One way Native Americans adapted to their environments was through their use of natural resources. They developed various methods of farming, hunting, fishing, and gathering based on the resources available to them. For example, tribes in the Great Plains relied on bison herds for food, clothing, and shelter, while tribes in the Northeast cultivated maize, beans, and squash together in a system known as the Three Sisters.
Another adaptation was the construction of different types of dwellings suited for their environments. In the harsh winters of the northern regions, tribes like the Inuit built sturdy, insulated igloos. In the Southwest, the Pueblo people constructed multi-story adobe buildings to take advantage of the region's warm, dry climate.
Furthermore, Native Americans developed an understanding of their local ecosystems and practiced sustainable management of resources. They had ecological knowledge passed down through generations, allowing them to live in harmony with nature and minimize their impact on the environment.
In order to provide a more detailed answer specific to a particular group or civilization of Native Americans, it would be helpful to narrow down the question to a specific tribe or region.
