What is a Tundra?
Tundras are biomes with low temperatures that don't have much diversity for life. They have harsh winters and short summers, causing snow to be almost always present. Animals have water almost all the time because of this snow. Because of the harsh weather, though, there is not much variety of animals in tundras. It is difficult to grow anything because of the frozen ground, so there isn't much for plant life, either.
