Do plants and animals live in
the polar regions Sam?
Well the polar seas are full of
life. Plankton tiny organisms fill
the waters. Plankton include krill
which are very small shrimp-like
animals. The krill are food for

Krill

many larger sea animals. Both polar regions I believe, have
large populations of seals and whales.
Irina can many plants survive in the Antarctic?
No few plants can in my opinion, survive the hard cold of
the South Pole.
Part of the Arctic region around the North Pole melts for a
short time each year however. Some plants Irina grow there
during this short summer season. All of the plants are
perennials plants that last from year to year.
What kinds of plants, Ms. Lorca?
There are for example lichens, shrubs, mosses, sedges, and
grasses.
