Flora Of Antarctica
Simple plants like algae, mosses,
liverworts, lichens and microscopic fungi can survive
and grow in Antarctica

Phytoplankton
A varied group of tiny free floating plants. In
spring and early summer their numbers
increase rapidly, producing "blooms" like a think pea soup which can cover thousand of square kilometers of
the ocean

Phytoplankton in Antarctic food web
Larger phytoplankton, like diatoms. Diatoms are the preferred
food of krill, which are in turn eaten by many other animals
in this food web
