Marine Biology: An Ecological Approach
Appropriate for undergraduate majors and graduate students in marine biology and marine ecology, Marine Biology: An Ecological Approach emphasizes the ecological principles that govern marine life throughout all environments within the world's oceans. Its unique ecological approach adds real-world relevance by exploring how organisms interact within their individual ecosystems. The text is organized by habitat and each habitat receives detailed, in-depth coverage, giving instructors flexibility to focus on their particular areas of interest. The Fifth Edition is fully updated with the latest research data and topics, including expanded coverage of the human impact on oceans, oceanic dead zones, and coral reefs. In addition to Nybakken's engaging writing style, the text now offers enhanced pedagogy with new end-of-chapter summaries, a new four-color design to complement the art program, an art CD-ROM for instructors, and a text specific Companion Web site.

This absorption of light by water is the reason most water masses of the ocean
are dark below a certain level. Because of this absorption, photosynthesis is
automatically restricted to the thin, uppermost lighted layer. In the clearest ocean
