It is a vast menagerie of small and microscopic organisms that comprise the foundation of the food web in coastal marine ecosystems. It starts with zooplankton adrift in turgid currents and bacterial colonies in mudflats, rock crevices and canopies of kelp and meadows of eel grass undulating in the tidal surges. Then come single-celled animals that feed on the colonies, and the larger predators that in turn feed on them.
