Marine Life, Energy, and Food Webs

Lecture no. 17 from the course: Oceanography: Exploring Earth's Final Wilderness

Marine Life, Energy, and Food Webs

Taught by Professor Harold J. Tobin | 34 min | Categories: The Great Courses Plus Online Science Course

Trace the path of energy and food through oceanic ecosystems, which have a far higher turnover of biomass than the terrestrial equivalents. As a result, most of what grows in the oceans is very quickly consumed. Learn why warm, temperate seas are often nutrient-poor compared with polar waters.
