Climax stage is achieved quickly in secondary succession as compared to primary succession. Why ?
The rate of succession of ecological science in secondary succession is more rapid than primary succession because soil is ready for subsequent succession. White in primary succession, succession starts from totally bare rockd that takes time to produce first habitate of plants because there is no method having nutrient elements.
