Document Summary
Aquatic life zones - aquatic equivalents of biomes. Salinity - the amounts of various salts such as sodium chloride dissolved in a given volume of water. Marine life zones - oceans, estuaries, coastal wetlands, shorelines, coral reefs. Freshwater life zones - lakes, rivers, streams. Plankton - organisms found in freshwater and saltwater. Ultraplankton - producers that make up the base of most aquatic food. Zooplankton - feed on phytoplankton and other zooplanktons. Nekton - second major aquatic organism; turtles, fish, and whales. Benthos - third type of aquatic organism; consists of bottom dwellers like oysters and sea stars. Decomposers - mostly made up of bacteria. Temperature, dissolved oxygen, availability of food, and availability of light all factor into the number of organisms you"ll find in a certain part of the ocean. Coastal zone - warm, nutrient rich, shallow water that extends from the high tide mark on land up until the continental shelf (submerged parts of the continents)
