Caribou are involved in a form of symbiosis in the tundra. Image by Flickr.com, courtesy of Billy Lindblom Tundra biomes exist at the northern and southern limits of habitable territory on the earth. Symbiotic relationships among organisms in the tundra can take many forms, from mutually beneficial relationships to relationships where one organism is harmed. Parasitism and a mutually beneficial relationship involving lichen are two prevalent forms of symbiosis in the tundra.

A biome is a living community characterized by its living and nonliving components, including climate, geography, and the types of plants and animals living in the biome. Biomes are composed of similar ecosystems and communities, which involve the relationships among the species living within them. There are eight distinct Biomes on Earth

In the tundra, conditions are cold, with an annual

average temperature less than 5ÿfd C, and

precipitation (mostly in the form of snow) less than

hat are the Types of Tundra Biome? Extremely cold temperatures and frozen, treeless landscapes characterize the tundra biome. While some sources claim that the word ‘tundra’ originates from the Kildin Sami term ‘tundar’, which means ‘treeless mountain track’ or ‘uplands’, others say that it has been derived from the Finnish ‘tunturia’, meaning ‘barren land’. The tundra is divided into two types: The Arctic Tundra, which is also present in Antarctica, and Alpine Tundra. The ecological boundary region, or ecotone, which demarcates the tundra and the growth of forest, is referred to as the timberline or tree line.

he Antarctic tundra occurs on various Antarctic as well as sub-Antarctic islands, which include the Kerguelen Islands, the South Sandwich Islands, and South Georgia.
