The Arctic ecosystem is characterized by its cold climate, ice-covered waters, and unique wildlife. It includes regions like the Arctic Ocean, Greenland, and parts of Canada and Russia. The ecosystem supports various species, including polar bears, seals, and migratory birds, which have adapted to the harsh conditions. Plant life in the Arctic is limited but includes hardy species such as mosses, lichens, and dwarf shrubs. The ecosystem is sensitive to climate change, with rising temperatures leading to melting ice and altering habitats. This impacts both wildlife and indigenous communities that rely on these resources for their livelihoods.
