The tundra is a biome characterized by an extremely cold climate, little precipitation, poor nutrients, and a short growing season. Other characteristics include low biodiversity, simple plants, limited drainage, and large variations in populations. There are two types of tundra: arctic and alpine.Arctic tundra is located in the Northern Hemisphere; alpine tundra is located at high elevations on mountains throughout the world. Tundra is also found to a limited extent in Antarctica â specifically, the Antarctic Peninsula.ife in any biome includes producers (plants and other photosynthetic organisms) and consumers (organisms that obtain their energy from producers). These consumers may be further classified as herbivores (plant eaters), carnivores (meat eaters), or omnivores (feed on a combination of animals and plants).
