>Answer:
In the ice-free regions (which make up about 2% of the continent), algae,
fungi, and bacteria live below the surfaces of rocks.  In the lakes of the
McMurdo Dry Valleys, biologists have also found algae.  Although these lakes
are fresh water lakes formed by melting glacial ice, a thick layer of ice
prohibits the exchange of oxygen with the lake water.

In contrast, the oceans surrounding Antarctica have abundant life and,
despite the near freezing temperatures, support many life forms, including
phytoplankton (small green plants that are essential for the marine food
web), diatoms, and algae.>
