1. Water Biomes
* Marine
* Freshwater

2. The Marine Biome ocean different organisms live in each area
* 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 3

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 4

5. Aphotic Zone- below 200m 5

6. 6

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

8. 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

9. 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

10. 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

11. Freshwater Animal Life
carp
trout
bass
bull frog
mallards

12. 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

13. They need sunlight to survive.
Water Biomes
Plankton are microscopic algae, plants, and other organisms that float on the surface of water biomes.
They need sunlight to survive. 13

14. Phytoplankton are important producers in water biomes.
They are the first step in many aquatic food chains 14

15. A Quick Review 6 * There are __________ land biomes: 2
Tundra
Tropical Rain Forest
