Answer:
Disturbance, season, and human activities (deforestation).
Step-by-step explanation:
The secondary succession never occurs on complete new habitat but on a area that is already colonized. The habitat area where secondary succession occur is disturbed and damaged.
The area damaged by fire can promote the chance of secondary succession. There are various factors like season, human activities for example deforestation and disturbance that affect the paths of secondary succession. The competition, colonization and trophic interation also affect the paths of secondary succession.
