  In the North East region of India, during the process of jhum cultivation, forests are cleared by burning and left for regrowth after a year of cultivation. How would you explain the re growth of forest in ecological term?

Answer:

                  Forests that are cleared by burning and left for re growth will show secondary succession. Since, soil is already present, the buried seeds open to germinate. Due to wind dispersal and some other natural forces, new seeds will be brought into the area and new species will colonise the forest again.
