Tundra vegetation is the plants that grow in regions with extremely cold temperatures year-round. There are two main types of tundra, the arctic and alpine tundra. These two tundras are home to similar types of small shrubs, grasses and mosses.Know More
Tundra is a specific type of biome, or world habitat, and it is characterized by freezing temperatures and treeless landscapes. The arctic tundra is located between the North Pole and the taiga region, and it remains frozen throughout the entire year. Vegetation in the arctic tundra must be able to survive months of continuous darkness in the winter and grow only for brief periods of time when the sun comes out in the summer. For this reason, plants in the arctic tundra are generally short. Small shrubs and grasses are common, as are lichens, mosses and perennial ferns. These have shallow roots, since they are unable to drive deep roots through the hard, frozen soil.
The alpine tundra is found throughout the world at high elevations. Examples of alpine tundra are the tops of the Himalayan Mountains in Southern Asia and the Andes Mountains in South America. Because these areas do not experience the same weeks-long darkness as arctic tundra regions, vegetation does not have to be quite as hardy. Short shrubs and grasses are still the main types of vegetation, but a wider variety of species are able to survive these harsh conditions.Learn more about Botany
Plants are necessary because they are a primary food source and provide the oxygen that is vital to animals' and humans' existence. A majority of the calories that people consume comes from plants, and most meat comes from animals that eat plants. Plants are at the bottom of the food chain, and animals could not survive without them. Plants also release the oxygen that humans and animals breathe.Full Answer >
The bearberry is a dwarf evergreen shrub adapted to Subarctic and Arctic climates. It can grow up to several meters in length. It creeps close to the ground as an adaptation to the extreme ripping winds of the tundra biome.Full Answer >
There are 15 invasive species that threaten tundra biomes, according to the Global Invasive Species Database, including Canada geese, dogs, cats, beavers, weasels, sheep, red foxes, European starlings and pine trees. Invasive species in the tundra push away native flora and fauna and reduce diversity in tundra biomes.Full Answer >
Plants do not need pure hydrogen to survive, but they do need hydrogen and oxygen molecules together in the form of water, which is a vital ingredient in the process of photosynthesis. This process uses water, carbon dioxide and energy from sunlight to create chemical energy.Full Answer >
