Arctic ecosystems are unique environments characterized by extreme cold, ice, and a variety of specialized flora and fauna. These ecosystems include both marine and terrestrial habitats, supporting species such as polar bears, walruses, and arctic foxes. The harsh conditions have led to adaptations that allow these organisms to thrive in a world of ice and snow. The Arctic is also home to diverse plant life, including lichens, mosses, and dwarf shrubs. These plants play a crucial role in the ecosystem, providing food and shelter for various animals. Climate change poses a significant threat to these ecosystems, impacting the delicate balance of life in the Arctic region.
