You will read about the roles different organisms play, from plankton to large predators, and how these species interact within food webs. The book also addresses topics such as coral reefs, migration patterns and the impact of human activity on marine environments. Written in accessible language, this guide is intended for readers who want a solid, factual foundation in marine biology without requiring prior scientific background.The ocean covers most of our planet, yet its ecosystems remain unfamiliar territory for many readers.
