15. 2 The Diversity of Ocean Life Classification of Marine Organisms classified according to where they live and how they move. Plankton • Plankton include all organisms—algae, animals, and bacteria—that drift with ocean currents. • Phytoplankton are algal plankton, which are the most important community of primary producers in the ocean. • Zooplankton are animal plankton.

Marine Life Zones Three factors are used to divide the ocean into distinct marine life zones: -availability of sunlight, -the distance from shore, -depth. Availability of Sunlight • The photic zone is the upper part of the ocean into which sunlight penetrates.

15. 2 The Diversity of Ocean Life Distance from Shore • The intertidal zone is the strip of land where the land ocean meet and overlap, or the zone between high and low tides. • The neritic zone is the marine-life zone that extends from the low-tide line out to the shelf break. • The oceanic zone is the marine-life zone beyond the continental shelf.

15. 2 The Diversity of Ocean Life Marine Life Zones Water Depth • The pelagic zone is open zone of any depth. Animals in this zone swim or float freely. • The benthic zone is the marine-life zone that includes any sea-bottom surface regardless of its distance from shore. • The abyssal zone is a subdivision of the benthic zone characterized by extremely high pressures, low temperatures, low oxygen, few nutrients, and no sunlight.

15. 3 Oceanic Productivity Oceanic Feeding Relationships • A trophic level is a nourishment level in a food chain. Plant and algae producers constitute the lowest level, followed by herbivores and a series of carnivores at progressively higher levels. • The transfer of energy between trophic levels is very inefficient.

15. 3 Oceanic Productivity Oceanic Feeding Relationships • A food chain is a sequence of organisms through which energy is transferred, starting with the primary producer. • A food web is a group of interrelated food chains. • Animals that feed through a food web rather than a food chain are more likely to survive because they have alternative foods to eat should one of their food sources diminish or disappear.
