# Polar Food Chains

Understand polar food chains — in the Antarctic, phytoplankton are eaten by krill, krill are eaten by fish and penguins, and penguins are eaten by leopard seals and orcas; in the Arctic, algae under ice feeds zooplankton, which feeds fish, which feeds seals, which feeds polar bears — and that tiny organisms like krill and plankton are the foundation of all polar life
