Detailed explanation-1: -So the correct option is ‘crustose lichens → foliose lichens → mosses → annual grasses → perennial grasses → shrubs → trees’
Detailed explanation-2: -The 5 Stages of Succession are Nudation, Invasion, Competition and Co-action, Reaction, and Climax or Stabilization. At the same location, a succession of biotic communities naturally emerges one after another until the Climax stage is reached.
Detailed explanation-3: -Primary succession occurs when disturbances (such as glacial advances and retreats, volcanoes, earthquakes, landslides, scouring floods, or very hot-burning fires) remove the soil and organisms from a site, leaving only bare rock, gravel, silt, or sand.
Detailed explanation-4: -Nudation. Invasion. Competition and Reaction. Stabilization. 23-Nov-2021
