How many different plants and animal species live in the tundra?

Answer 1

mosses, grasses, lichens, sedges, and shrubs. About 400 types of flowers bloom in the growing season, which lasts just for 50-60 days. Except for a few birches in the lower altitudes, no trees grow in the tundra. Because of the permafrost, trees cannot send their roots into the ground. Although in some parts of the tundra willows do grow, but only up to about 8 cm, or 3 inches, high. Developing over thousands of years, most of the vegetation have adapted to the conditions in the tundra by growing in a dense mat of roots. Except where the soil is fertilized by animal droppings, the soil is low in minerals and nutrients.

Being too dry and cold for vegetation to grow, the Antarctica tundra is mostly covered by large expanses of ice fields. However, in some parts of the region, especially the Antarctic Peninsula, there are areas where there is rocky soil which can support vegetation. The plant species that exist here are aquatic and terrestrial species of algae, which occur in the exposed soil and rock areas around the shore, liverworts, mosses, and lichens. The two flowering species of plants, the Antarctic pearlwort and Antarctic hair grass can be found in the western and northern parts of the Antarctic Peninsula.

48 species of land mammals occurring in the tundra biome, there are surprisingly large numbers of each species. The tundra animals mainly are slightly modified forms of deer, bears, foxes, wolves, rodents, hares, and shrews. In North America, there are large caribou herds, which are called reindeer in Eurasia, which feed on plants and lichens. Smaller musk-oxen herds also roam about the frozen regions. The predators of the tundra biome are polar bears, arctic foxes, and wolves. Some of the smaller mammals are lemmings and snowshoe rabbits.

Answer 2

The tundra is not a plants best place to grow because perma frost (the permanently frozen soil) that is about a finger-length under the surface in the summer months prevents the plants' roots from growing as long as they need. Because of the fact that plants can not grow their roots out, most of the tundra's plants are low shrubs and trees like dwarf willows and birches less than knee high. Mosses are also another type of vegetation that grow on the tundra, but the vegetation that has populated more than any other is the lichen which is a cross between fungus and algae.
