Here's why:
* Biome: A large-scale ecological community with a distinctive climate and a characteristic set of plants and animals. The dominant vegetation type is a key factor in defining a biome. For example, grasslands, forests, deserts, and tundras are all biomes.
While other terms can be used to describe plant communities based on dominance, they are not as broad as "biome":
* Dominant species: A species that is particularly abundant in a community.
* Community: A group of interacting populations of different species living in the same area.
* Habitat: The natural environment in which an organism lives.
