Biome

The video explores the concept of biomes, which are large geographic biotic units with similar life forms and environmental conditions. It covers five major biomes: aquatic, desert, forest, grassland, and tundra. Aquatic biomes include freshwater and marine ecosystems, while desert biomes are characterized by extreme dryness. Forest biomes are diverse, with tropical, temperate, and taiga forests. Grasslands are dominated by grasses, and the tundra is the coldest biome. Each biome has unique abiotic and biotic components.
