How does the artic ecosystem differ from the Antarctic ecosystem?

The Arctic ecosystem is primarily a land-based environment surrounded by sea, characterized by sea ice, tundra, and a variety of terrestrial and marine species, including polar bears and Arctic foxes. In contrast, the Antarctic ecosystem is largely a continent covered by ice, with a focus on marine life, including seals, penguins, and a diverse range of krill and other oceanic species. Additionally, the Arctic is inhabited by indigenous human populations, while Antarctica has no permanent residents. These differences lead to distinct ecological dynamics and species adaptations in each region.
