Life in a frozen world : wildlife of Antarctica
(Book)

Includes bibliographical references.

"Although a frozen continent, Antarctica supports a variety of wildlife on and around it. Bone-chilling cold and wind, combined with dry conditions, form a hostile environment but certain species have adapted to live there successfully. From the giant to microscopic algae that provide photosynthesis and the animals depending on these producers to support the food web, to the apex predators reliant on the sea ice and life there, Antarctica forms a delicate and balanced ecosystem that has thrived for ages. Unfortunately, changes have begun that may upset the balance and eliminate many of the life forms that call it home" --,Provided by publisher.
