Why is secondary succession faster than primary succession? Explain. (CBSE 2019 C)
Secondary succession is faster than primary succession: It has a secondarily based area built-in soil organic matter. It is biologically fertile. Underground parts, some seeds, and remnant species quickly give rise to a new community. Secondary succession takes 50-100 years to complete in grassland and 100—200 years for the development of the forest. It takes short time as com¬pared to primary succession.
