Polar ecosystems are unique environments found in the Arctic and Antarctic regions. These areas are characterized by extreme cold, ice, and snow, which create challenging living conditions for plants and animals. The primary vegetation includes mosses, lichens, and some hardy flowering plants, while the animal life consists of species like polar bears, seals, and various types of penguins. These ecosystems play a crucial role in the Earth's climate system. The ice and snow reflect sunlight, helping to regulate global temperatures. Additionally, polar regions are vital for scientific research, providing insights into climate change and its effects on biodiversity and ecosystems worldwide.
