Sea Food

A richly illustrated introduction in verse to food chains and food webs in the ocean, including the basic food pyramid "rule of ten," e.g., it takes 200 lobsters to feed 20 octopuses, which will feed 2 sharks. Four food chain habitats include two in the open ocean, one on a rocky bottom, and one in the cold Antarctic. Scale drawings of familiar objects illustrate the sizes of the marine creatures. The book explains the difference between a food chain and food web. A glossary defines terms such as plankton and algae.
