After avoiding hungry predators like seals, wolves and bears on their upstream migration to spawn and die, the carcasses of chum salmon are swept downstream and pile up on a boulder. Bears and scavengers spread salmon carcasses into the surrounding forest, where the nutrients from their decaying bodies will fertilize the trees. Meanwhile the forest regulates the waters that rear the next generation of salmon. Ocean and forest are not distinct entities here - they nourish each other in a continuum.
