  2. Estuaries

  3. Marine Ecosystems A water environment, from pond to ocean, in which plants and animals interact with the chemical and physical features of the environment. They contain a large diversity of organisms and include oceans, salt marshes, estuaries, lagoons, mangroves and coral reefs

  4. Terrestrial Ecosystems An interaction between living and nonliving things found only on landforms.

  5. Buffer Zones The areas that buffer or border between water (marine) and land (terrestrial) habitats

  6. Estuaries Partly closed coastal body of water that is connected to one or more rivers (freshwater) and the ocean (saltwater) that contains a mixture of salt and fresh water (brackish water) and provide habitats for large amounts of aquatic organisms

  11. Nutrients Chemicals that organisms need to live and grow; substances taken in from an organism’s environment that are used in an organism’s metabolism

  12. Dissolved Gases A situation that occurs when a gas becomes dissolved in another solute due to pressure. Ex- Soda (Carbon Dioxide is dissolved in another liquid)

  13. Minerals Naturally occurring substance that is required by living organisms as part of their dietary nutritional intake

  14. Upwelling The wind driven motion of dense, cooler, nutrient rich water moving toward the ocean surface replacing the nutrient deficient surface water

  15. Deep Ocean Ecosystems The physical environment and all the living things that make up the deep ocean and deep ocean ridges

  16. Bioluminescence The biochemical emission of light by living organisms
