Predator Prey examples are, bear and fish, snake and fish, catfish and crawdad.
An example of symbiosis for streams and rivers is, nile crocodile and the crocodile bird. When the crocodile is laying around the river banks, it tends to leave its mouth wide open. This allows the bird to land in its mouth and eat all the bits and pieces of food left in the crocodile's teeth. The crocodile gets a cleaning of his mouth and the bird gets food from the crocodile's mouth.
