 | | marine biology, study of ocean plants and animals and their ecological relationships. |
 | | Marine organisms may be classified (according to their mode of life) as nektonic, planktonic, or benthic. |
 | | The distribution of marine organisms depends on the chemical and physical properties of seawater (temperature, salinity, and dissolved nutrients), on ocean currents (which carry oxygen to subsurface waters and disperse nutrients, wastes, spores, eggs, larvae, and plankton), and on penetration of light. |
