Life in the Freezer
The Bountiful Sea

The life in Antarctica is almost completely supported by the sea. This is the main source of food for each of the large animals that inhabit the continent, including seals, whales, and sea birds.

Key Concepts: Sea ice, icebergs, glaciers, Antarctic tundra, keystone species, symbiosis, commensalism, scavengers, niche, mating rituals, adaptations.
