Names / Roles:

  • [Grory]           (Leader and Wiki Writer ) 
  • [Sharifah]     (Researcher)
  • [Zahirah]          (Researcher)
  • [Maisarah]      (Researcher) 



In this section, include a brief description of the allocated ecosystem. You should include the following information:

  • Location of the ecosystem-The polar regions are the areas that surround Earth’s North and South Poles.The area surrounding the North Pole is called the Arctic and includes almost the entire Arctic Ocean and northern areas of Europe, Asia, and North America. The area surrounding the South Pole is called the Antarctic and includes the continent of Antarctica and parts of the surrounding Southern Ocean. 
  • Description of ecosystem- Polar are the icy wastes of the continental ice caps and the frozen pack ice of the ocean
  • Biodiversity of ecosystem (richness of life in ecosystem)  -The only 'plants' here are specialised forms of cold-loving algae that grow on the surface of snow. Only animals that don't rely on vegetation - such as penguins, seals and polar bears - are able to live here





Physical Factors



  • Light in Polar Regions-Aurora,

The aurora borealis (northern lights) and its southern equivalent aurora australis (southern lights), surround both the north and south magnetic poles. They are best seen on a cold clear night and often appear as hanging curtains of light in the sky.

  • Temperature in Polar Regions-The average temperature in Antarctica in summer is 20°F (-6.66°C), while the average temperature in winter is -30°F (-34.44°C). Note: Antarctic winter months are the reverse of those in the Northern Hemisphere.
  •  A Fun Fact-  The coldest temperature ever officially recorded on Earth was -129°F (- 89.2ºC), at Vostok, Antarctica, on July 21, 1983.The coldest temperature in the Arctic was -94ºF (-67.8ºC) at the village of Verkhoyansk, Siberia.
  •  Water in Polar Regions-There is nothing much to talk about Water in the regions and but water also can be refer to Ice caps in the regions. In North Pole,The area covered by sea ice ranges between 9 and 12 million  and contains about 2.6 million of ice. In South Pole,It covers an area of about 14.6million  and contains 25–30 million of ice.
  • A true fact-Ice caps in the regions are melting due to Global Warming.You may think that it does not have to do anything with your surroundings.But it has to do, the water from the melted ice caps can flow.Then the water makes the water level higher.Countries near Antarctic and Arctic ocean can be affected with flooding.
  • Air in Polar Regions- How does it smell like in the regions? There is no information showing how it smell there.But when I searched Air in Polar Regions,it showed about Air Pressure. 




Classification of Living Organisms

Classify at least eight of the living organisms found in the allocated ecosystem into the categories below:

  1. Producers-
  2. Primary Consumers
  3. Secondary Consumers
  4. Tertiary Consumers 
  5. Decomposers

For each of the living organism, find a picture and write a short description on the organism. You may wish to include feeding habits, region in the ecosystem where it is normally found etc. 




Food Web 

Create a food web using at least eight of the living organisms listed above. You may wish to use Microsoft PowerPoint to create your food web. Save your food web as a picture. Finally copy and paste your picture in this section of your wiki. 




Interrelationship in Ecosystem

Give at least one example for each of the following relationships in the ecosystem:

  1. Predator-prey relationship
  2. Parasitism
  3. Mutualism




Useful Links

Plagarism is a strongly discouraged.


Include the links of all websites you obtained information from to complete your ecology wiki. 

For example:

Wild World @ nationalgeographic.com ( http://www.nationalgeographic.com/wildworld/terrestrial.html )

hi, I think you forgot to enter your interrelationship portion. Please add more pictures too.

You also miss out on the classification of living organisms

I want my group members to do 😳
