Global Biomes and Their Characteristics

This video provides an overview of global biomes, explaining their characteristics and the abiotic factors that influence them. It covers various biomes, including tropical rainforests, hot deserts, tropical and temperate grasslands, Mediterranean, deciduous and coniferous forests, tundra, and polar regions. Each biome's unique features, climate, and adaptations of flora and fauna are discussed.
