  1. Water Biomes *Marine *Freshwater

  2. The Marine Biome ocean * The marine biome is the _________________ biome. • covers about 70% of the Earth * has salt water * About 95% of water on Earth is saltwater * Organisms that live in the ocean are able to live in the salt water. * sunlight, water pressure, and water movement affect the organisms too • because of these things, the ocean is divided into different areas • different organisms live in each area * The water that is very deep has cold temperatures, high pressures, and is very dark

  3. Photic Zone- above 200m Made up of the euphotic & disphotic zones Sunlight penetrates Plant life and animal life is abundant

  4. Aphotic Zone- below 200m Sunlight DOES NOT penetrate There are no plants Animal life is highly specialized Many of the animals of the deep ocean have a special adaptation known as bioluminescence

  5. Aphotic Zone- below 200m

  6. Marine Plant Life • Many of the plants live near the top of the water • they need the sunlight to help them grow and make food barnacles coral

  7. Marine Animal Life • Most marine organisms live near the top of the water or close to land • Many animals dig down into the sand or hang on to rocks, so they do not get lost in the sea • Other larger animals live where the water is deep barracuda star fish clown fish crab flashlight fish green sea turtle killer whale shrimp

  8. The Freshwater Biome salt * Freshwater means it does not have _______________ in it • * Includes still water and moving water • * Examples of still water * Examples of moving water • * lakes and ponds * rivers and streams

  9. Freshwater Plant Life * Many of the plants that live in freshwater have strong roots to keep them in one place. * Some plants grow around the edge of the lake or float on the top of the water cattail water lily

  10. Freshwater Animal Life carp trout bass bull frog mallards

  11. A Special Kind of Water * Estuary * border between a freshwater biome and a marine biome * are salt marshes, lagoons, swamps, and mouths of rivers that go into the ocean * are a mixture of freshwater and salt water * some scientists believe estuaries are another biome, other scientists believe estuaries are an ecosystem * not very deep, so sunlight gets to all the water * have many fish and plants * also known as brackish water

  12. Plankton are microscopic algae, plants, and other organisms that float on the surface of water biomes. Water Biomes They need sunlight to survive.

  13. Phytoplanktonare important producers in water biomes. Water Biomes They are the first step in many aquatic food chains

  14. A Quick Review 6 * There are __________ land biomes: Tundra Tropical Rain Forest ____________________ ____________________ Taiga Grassland ____________________ ____________________ Deciduous Forest Desert ____________________ ____________________ 2 * There are __________ water biomes: Marine Freshwater ____________________ ____________________ estuary * The special kind of water is an ___________________.
