What grows there?
1700 species of plants grow in the Arctic tundra, providing
food for herbivores such as reindeer, musk oxen, lemmings,
arctic hares and squirrels. These include low shrubs, grasses, mosses and liverworts. Plant life in the Antarctic is not as plentiful; only about 1% of the continent is ice free.
There are just two species of higher plants, one grass, a small
flowering alpine, around 100 species of moss, 300-400 species
of lichens and 25 types of liverworts.
