What are the different between plants formation and bioms

Answer 1

Plant formation is an old term used by Frederic Clements (circa 1900 - 1916) used to group the successional stages of an entire sere. It's sort of a way of classifying groups of plant communities that change over time due to disturbance. You don't see it in use much any more.  

Answer 2

Biome: A biome is like where type of habitita in which something lives. (Grassland, dessert, mountains.....)
