The video explores the Arctic tundra, the coldest biome, characterized by permafrost and extreme temperatures. It discusses plant and animal adaptations necessary for survival, such as shallow roots, thick coats, and migration. The tundra's short growing season and long daylight hours lead to a burst of life, attracting migratory species. The video highlights the interactions between species, the impact of climate change, and the unique strategies employed by flora and fauna to thrive in this harsh environment.
