Resource Utilization and Succession

Groups of microbes often utilize the "waste" others, thus establishing commensalistic relationships; this is clearly seen in environments with a mixture of limited amounts of oxidants that can serve as terminal electron acceptors, such as oxygen, iron (or manganese), nitrate, sulfate and carbon dioxide (e.g., Winogradsky column)

Example of a succession based on terminal electron acceptor availability:
