- 3. WHERE THE ECOSYSTEMARE? The Arctic is a polar region located at the northernmost part of the Earth. The Arctic consists of the Arctic Ocean and parts of Alaska (United States), Canada, Finland, Greenland (Denmark), Iceland, Norway, Russia, and Sweden.
- 4. Weather condictions TheArctic's climate is characterized by cold winters and cool summers. Precipitation mostly comes in the form of snow. The Arctic's annual precipitation is low, with most of the area receiving less than 50 cm (20 in). High winds often stir up snow, creating the illusion of continuous snowfall. Average winter temperatures can be as low as −40 °C (−40 °F), and the coldest recorded temperature is approximately −68 °C (−90 °F).

- 6. Types of plants Types of animals Arctic vegetation is composed of plants such as dwarf shrubs, graminoids, herbs, lichens and mosses, which all grow relatively close to the ground, forming tundra. Colder summer temperatures cause the size, abundance, productivity and variety of plants to decrease. Herbivores on the tundra include the Arctic hare, lemming, muskox, and caribou. They are preyed on by the Snowy owl, Arctic fox and wolf. The polar bear is also a predator, though it prefers to hunt for marine life from the ice. There are also many birds and marine species endemic to the colder regions. Other land animals include wolverines, ermines, and Arctic ground squirrels.
- 7. Non-living things TheArctic includes sizable natural resources (oil, gas, minerals, fresh water) to which modern technology and the economic opening up of Russia have given significant new opportunities. The interest of the tourism industry is also on the increase.
- 8. What is afood chain? Food chains show how plants and animals get their food (energy). It shows how energy is passed from one organism to another, with the arrows representing the direction of energy flows. What is a food web? A food web is a lot of food chains all put together to show how the plants and animals in an entire ecosystem rely on each other. Figure 2 shows a basic food web for an arctic ecosystem.
- 10. Conclusion In ourcountry, Spain, at the end of the century, the beaches of Benidorm, Marbella and San Sebastian will be submerged under floods of water, as most of the infrastructure situated in coastal areas. The rising temperatures and melting ice caps will be the main cause. Then, the Arctic is also a matter of Spain
