. Further decomposition of these annual grasses lead to replacement by perennial grasses like Cymbopogon, Heteropogon etc. Some small animals also invade the habitat. d) Shrub stage - Further weathering or rocks and death of herbs make the habitat more suitable for the growth of shrubs like Rhus, C..
