Answer;
C. Live in Antarctic ice
Explanation;
• Archaebacteria are the oldest living
organisms on earth. They are prokaryotes and
unicellular. Archaebacteria are found in very harsh
conditions such as at the bottom of the sea or in
volcanic vents.
They slowly gave way to modern
organisms when the Earth's conditions settled
down and oxygen was introduced to the
atmosphere.
There are three phyla, or groups, of
archaebacteria. methanogens, which harvest
energy into methane, halophiles which live in
extreme salt conditions and thermoacidophiles
which survive in extreme temperature conditions.
