Answer:
disturbance plays in competition.
Explanation:
Fire-dependent pitch pine trees (Pinus rigida) is replaced by black locust (Robinia pseudoacacia) because of disturbance that occurs in the environment naturally. When disturbances occur naturally, they provide conditions that favor the success of different species over the native organisms. The native organisms are vanished from that ecosystem due to changing of environmental conditions and other organisms settle there which can survive in that environment.
