Biomes and Their Characteristics

The video provides an overview of biomes, large ecological areas defined by climate and vegetation. It covers tundra, desert, aquatic, grassland, and forest biomes, detailing their characteristics, climates, and biodiversity. Tundra is cold with low biodiversity, deserts are arid with specialized flora and fauna, aquatic biomes include freshwater and marine regions, grasslands vary by hemisphere, and forests are diverse and crucial for climate regulation.
