not true.  a very bad generalization.  all i will grant you is that grasses arose recently in botanical evolution because they are highly successful competitors to repopulate exposed, unforested soils -- especially drylands with lower levels of rainfall and soil mineral nutrient supplies.  the grasses and their herbaceous companions quickly cover these denuded niches in the biosphere to shade and cool the land, filter rain and snowfall, and begin to rebuild subsoil biomasses -- living, dead, and decaying.

  forests tend to hold their biomass within the above ground parts and prairies/grasslands/ag. tend to hold biomass closer to or below the ground level.
