Tundra habitat is found in the Arctic, beyond the permanent ice pack that surrounds the North Pole. It is a habitat of contrasting seasons, with temperatures as low as –76 degree Fahrenheit (–60 degrees Celsius) in the winter and almost no sunlight, to temperatures as high as 77 degrees Fahrenheit (25 degrees Celsius) in the short summer season.
Wetland habitats are complex and found all over the planet, from the polar regions to the tropics. They include marshes, swamps, bogs, and lagoons, and they are constantly changing, based on the seasons, water levels, tides, and migrations of birds and mammals. Wetlands may have areas of permanent standing water, although that may change with rainy and dry seasons, or they may be areas of damp, muddy, waterlogged soil.
