Here's why:
* Biomes are large-scale ecosystems: They cover vast geographic regions and are characterized by specific climate conditions, plant and animal life, and soil types.
* They are made up of diverse habitats: Within a biome, there can be many different habitats, like forests, grasslands, wetlands, and deserts.
* They are "loosely defined": Biome boundaries are not always clear-cut, and there can be gradual transitions between different biomes.
Some examples of biomes include:
* Tundra: Cold, treeless regions with permafrost.
* Taiga: Coniferous forests with long, cold winters.
* Temperate deciduous forest: Forests with trees that lose their leaves in autumn.
* Grassland: Open areas dominated by grasses.
* Desert: Dry, arid regions with low rainfall.
