Final answer:
Forest fires are necessary to help rid the area of old and sick trees.
Step-by-step explanation:
The statement that these fires are necessary to help rid the area of old and sick trees is True.
Forest fires play an important role in ecological processes, including maintaining the health of forest ecosystems. One of the benefits of fires is that they help clear out dead and diseased trees, allowing new, healthier trees to grow.
For example, after a forest fire, the burnt area may be gradually replaced by small grasses, which are then replaced by small trees and shrubs. This is an example of the later stages of secondary succession, where new trees grow in the place of old ones.
