Biomes and Their Characteristics

The video explores Earth's biomes, focusing on their relationship with climate. It covers forest, grassland, chaparral, desert, and tundra biomes, detailing their characteristics, flora, and fauna. The video also discusses the impact of latitude and precipitation on these ecosystems. Finally, it introduces the Köppen climate classification system as a future topic.
