Antarctica has a fragile and unique polar ecosystem characterized by extreme conditions, low biodiversity, and a delicate balance. Despite its harsh climate, Antarctica supports life adapted to its cold environment, including phytoplankton, krill, seals, penguins, and various seabirds. This ecosystem is highly interdependent, with microscopic organisms like phytoplankton forming the base of the food chain. The isolation and sensitivity of this ecosystem make it vulnerable to disturbances from climate change and human activity, highlighting the importance of preserving Antarctica’s pristine environment to maintain its ecological balance.
