Phytoplankton live in the Southern Ocean that surrounds Antarctica, and this is their natural habitat. In the Southern Ocean -- and in other large ocean areas, their survival on minerals and photosynthesis is limited by their access to iron.
They do, however, survive in the Southern Ocean and form the base of the short food chain there.
Remember, liquid water is always warmer than the ambient air in Antarctica.
The temperature of the Southern Ocean has a narrow range; from about -2°C to 0°C. Sea ice freezes at about -1.8°C which is about 1° lower than the freezing point of many species of fish. Of the 20 000 species of fish world-wide, there are only about 200 species in Antarctica.
Fish of the Antarctic waters show the most remarkable adaptations to these cold temperatures. Many species accumulate sodium, potassium, chloride ions or urea which lower the freezing point of their bodies. Others have glycoproteins which, like anti-freeze, inhibit the growth of ice crystals
Whales are sea animals and do not survive on land. Antarctica is a continent. Whales survive in the Southern Ocean, because that is their home. There is a rich food chain there and the water is warmer than it is on the continent.
Krill that live in the Southern Ocean that surrounds the Antarctic continent, survive in these waters because it is their natural habitat. In the extreme cold, the animals grow more slowly, live longer and in this case, form the base of the ocean's food chain.
No animal lives on Antarctica: it's too cold and there is no food chain.
Animals that breed on Antarctica's beaches, including sea birds and sea mammals, breed there because there are no land predators. These animals live in sea water, where they find their food and the warmth of liquid water.
they are single celled organasms... what do you expect from such lowly creatures???
Fish are sea animals, and do not live on the Antarctic continent. So long as the sea is liquid, sea animals -- fish -- find this a natural habitat.
Krill is the bottom of the short food chain in the oceans around Antarctica.
No. Krill breed in the Southern Ocean that surrounds the continent of Antarctica. They do not breed on land.
Krill are the foundation of the food chain in the Southern Ocean that surrounds Antarctica.
There is no commercial krill fishing in the Southern Ocean that surrounds Antarctica.
because they ike krill
Krill
Krill survive in the Southern Ocean which surrounds the Antarctic continent.
Whales around Antarctica eat, krill, plankton and fish!
Antarctica is a continent and krill are sea animals. The liquid sea is always warmer than the ambient temperature in Antarctica. The cold Southern Ocean is a natural habitat for krill.
krill
Krill thrive in the continent of Antarctica
antarctica krill can live to 11 years but some whales eat them before they get to 11 years
