What habitat is the arctic tundra?

Arctic tundra is a type of habitat found in the northernmost regions of the world, such as northern Alaska, northern Canada, northern Russia, and Greenland. It is characterized by low temperatures, permafrost, and cold-adapted plants and animals. The average temperature in the Arctic tundra is below freezing for most of the year, and the ground is permanently frozen, which prevents trees from growing. The plants that do grow in the Arctic tundra are typically low-growing and have a short growing season. Some common plants include mosses, lichens, grasses, and sedges. The animals that live in the Arctic tundra are also well-adapted to the cold climate. Some common animals include polar bears, arctic foxes, musk oxen, reindeer, and various species of birds.
