What are polar tundras?

Polar Tundra is the coldest of all biomes of the tundra biome, and its in the northern hemisphere. It's considered the world's youngest biome. It has very little plants, and has animals like polar bears, grey wolves, lemmings, rabbits, ravens, falcons and penguins. The soil in artic tundra has little nutrients so the amount of vegetation is small. Some plant life in the artic tundra include lichen, moss, flowers, and shrubbery. The ice cold rivers are homes for fish like salmon and other freshwater fish. When it rains, it sometimes creates small ponds that are mating spots for mosquitoes and flies. In the winter, the birds migrate south, which creates constant change in the animal population.


Do you think our biome has more or less biodiversity than yours?

  1. I think my biome (Tropical Rainforest) has more biodiversity than yours. Though your biome has a variety of animals, it doesn't have a variety of plants. My biome has many of both plants and animals.

  2. I think my biome, Temperate Grasslands, have more biodiversity than yours because it's an easier environment for organisms to grow in.
