Plants
There is very little plant life in the Antarctic Ocean. The main plant is Phytoplankton but other plants include types of algae and lichen. Plants play a large role in the ecosystem, since there are so few species there is an abundance of what species do thrive in the antarctic in order to supply enough nutrients for the rest of the food chain. These plants have a tough time because since the Antarctic Ocean is located near the south pole there can be areas of the Ocean that go long times without sunlight, but on the other hand there will also be stretches of time were the sun will not set in those same places.
