Answer: Plants such as tree cones depend on wildfires in order to pass through a regular life cycle.
Explanation:
Some Tree cones need wildfires to enable them pass through a life cycle because the heat produced melts the substance that covers the pines thereby enabling the pines to open up and spread their seeds.
Wildfires are therefore essential to the continued survival of trees such as these because without wildfires, these trees might never go through the entirety of their life cycle by dispersing seeds and if this continues it would spell doom for the survival of the species.
