When you eat like a cormorant - which is a lot - you poop like a cormorant - which, again, is a lot. This potent concoction falls from the cormorant's precarious perch, entering the food chain only a few feet below. Bacteria then grow in this enriched, (let's call it fertilized) water. Soon the plankton count their lucky stars while feeding on this heaven-sent bounty. Small invertebrates and protozoans gorge on the plankton, and on and on it goes up the line. Shrimp, crabs and sardines bless father cormorant before gorging on the millions of minute krill or the collected organic detritus they leave behind.
