FEATURES 
The tundra biome is considered a carbon 
dioxide sink because it stores more carbon 
dioxide than it gives off. 
There are very few trees that grow in the 
tundra biome.  
The ecotone (or ecological boundary region) 
between the tundra and the forest is known 
as the tree line or timberline.
