The word ecosystem refers to the combined physical and biological components of an environment; these organisms form complex sets of relationships and function as a unit as they interact with their physical environment. Ecosystems are constantly changing naturally‚ and they’ve got a specific and stable climax‚ equilibrium. Living as well as non-living factors may have an impact in an ecosystem such as the impact of humans in ecosystems by hunting‚ fishing‚ agriculture etc. or climate change

tundra is a biome where the tree growth is hindered by low temperatures and short growing seasons The Tundra Biome is one of the most unique Biomes in the world. Covering one tenth of the earth’s land area it is a substantial Biome. Tundra is the coldest of all the biomes. Tundra comes from the Finnish word tunturi‚ meaning treeless plain. It is noted for its frost-molded landscapes‚ extremely low temperatures‚ little precipitation‚ poor nutrients‚ and short growing seasons. Major problems With

Delgado‚ Karina Professor Tuscano NR 2 TTH AM 27 January 2015 Tundra Biomes In the world there are about twelve biomes. The major biomes include deserts‚ forests‚ grasslands‚ tundra and several aquatic environments. A biome is large geographical area with special plants and animal groups and they are adapted to that type of environment. The Tundra biome is the coldest biome of the many biomes. It is separated into two types which are the arctic and alpine. The following information was gathered from a

Luis Perez 11/23/10 6th The Tundra Biome Being the coldest and least filled with plant life‚ the tundra biome is noted as frost-molded landscapes with extreme temperatures. The tundra biome has low biotic diversity‚ low precipitation‚ and all around low‚ cold temperatures. The average temperature of the biome varies going from -25’C to 3’C between the months of January to July‚ then reverting from 3’C to -25’C between the months of July to December. Through those temperatures it causes a cycle

Mikhail Kashtelyan The Consequences of a global temperature rise on arctic ecosystems Nowadays the climate is changing‚ in more exact words the global temperature is raising every year. Those climate changes may cause a lot of different disasters and brake of ecosystems. A place that is really endangered of global temperature rise is arctic. Arctic is a very big icy landmass that is located north of the Arctic Circle. Arctic contains a lot of different kind of species. If the icy landmass is going

Intro The tundra is a cold freezing place that doesn’t frequently have much rainfall. The average temperature is 10-20 degrees fahrenheit. The tundra also have a wide variety of plant life and few trees that have a creative way to adapt to their environment. The tundra has many amazing animals that has its own effect. In the tundra some animals are become engendered because the

because of many things‚ including temperature‚ rainfall‚ location‚ and altitude. Tundra and Tropical Rainforest are two contrasting biomes‚ different in many ways. First of all‚ location. Tundra is located in the coldest parts of the world‚ like the most northern parts of America (i.e. Alaska) and Greenland. Alpine tundra can be found in places of high altitude‚ like the top of a mountain or similar. Tundra covers about 20% of the world’s surface‚ yet only 4 million people live there. That

TUNDRA CLIMATE The tundra biome is characterized by extremely cold temperatures and treeless‚ frozen landscapes. There are two types of tundra‚ the arctic tundra and the alpine tundra . ARCTIC TUNDRA The arctic tundra is located in the extreme northern hemisphere around the North Pole. This area experiences low amounts of precipitation and extremely cold temperatures for most of the year. The arctic tundra typically receives less than 10 inches of precipitation per year (mostly in the form of

The Tundra has snow everywhere and has very short growing seasons which means plants are hard to grow and farmers or whoever is planting crops need to plant early summer or fast enough before summer ends.

framework consists of 15 ecozones. Within these are 194 ecoregions. Arctic Cordillera This ecozone incorporates vast polar ice fields and has some of the most spectacular alpine glacier scenery in the world. Massive ice caps and glaciers mask many of the rugged mountains. Some of Canada’s highest but least-known peaks are found here‚ towering over U-shaped valleys and deep fiords that extend many kilometres inland. This Arctic Cordillera occupies the northeastern fringe of the Northwest Territories
