What are the secondary consumers in a salt marsh?

In a salt marsh, secondary consumers primarily include various species of birds, fish, and small mammals that feed on primary consumers such as insects, crabs, and other small invertebrates. Common examples of secondary consumers in this ecosystem are herons, egrets, and certain fish species like mullet and flounder. These organisms play a crucial role in the food web by regulating the populations of primary consumers and contributing to the ecological balance of the salt marsh.
