6. Aquatic Biomes: Life in the Water
Lakes, oceans, streams, ponds and other bodies of water
Marine Biome- ___________________
Freshwater- no saltwater

7. Marine Biome Ocean Life
Oceans contain the largest amount of __________ (Living material) than any other biome
Ecologists break up the marine biome into 2 Zones
Photic Zone
Aphotic Zone

8. Photic and Aphotic Zones
Photic Zone- The part that ____________________________ gets to
Plankton- microscopic organisms that float on the water
Shrimp, jellyfish, worms, crabs, snails, whales all eat plankton
___________________ Zone- The deeper water that never gets sunlight
Almost 90% of the ocean is more than a mile deep
Life in this zone depends on plankton in some way for food

10. Esturary & Intertidal Zone
Esturary- a coastal body of water, partially surrounded by land, where freshwater and salt water____________________________
Intertidal Zone- The part of a shoreline that lies between high and low tides

11. Freshwater Biome Lakes, Rivers, ponds
Shallow water plants are highly productive
Include fishes, algae, protests, mosquito larvae, tadpoles, and crayfishes

12. Freshwater Biome
Temperatures vary within a lake- gets ______________ as you dive _____________
Sunlight rarely reaches the bottom of deep lakes so plants and algae can’t grow
Therefore, as you go deeper in a lake the amount of populations _______________
Bacteria will break down the decaying matter at the bottom of the lake

13. All kinds of weather- snow, rain, hot, cold, humid
Terrestrial Biomes
Land
All kinds of weather- snow, rain, hot, cold, humid
6 Kinds
Tundra
Taiga
___________
Grassland
Temperate Forest
Tropical Rain Forests

14. Tundra Summer days can be long, but growing season is short
Mosquitoes and other biting insects are some of the most common animals
Foxes, Snowshoe hares, owls and hawks
Treeless land with long summer days and short periods of winter sunlight
Circles the north pole
Temperatures never get above Freezing- Burr!
Permafrost- layer of permently frozen ground

15. Taiga
Northern Coniferous forest of _______, fir, hemlock and spruce trees
Lies south of Tundra- Stretches across Canada, Northern Europe, and Asia
Develops from decaying coniferous needles and is __________ and lacks minerals in soil
Trees provide food and shelter for animals
Snowshoe Hare, Caribou, Lynx

16. Desert Driest Biome- Less than ____cm of rain per year
Almost nonexistent plant life
Cacti have a thick waxy coat to prevent water loss
Animals- small herbivores that seek shade during the day and come out at night
________________ doesn’t have to drink water- obtain their water through their food
Foxes, coyotes, hawks, owls, and roadrunners feed on snakes, lizards and small mammals

17. Grassland ___________ centimeters of rain per year
Large Communities covered with Grasses and small plants
______________ of Terrestrial biomes
Grasses die off during the winter leaving decay products to build up in the soil
Large Herding animals like bison and buffalo
Wolves, Coyotes, and Humans are the carnivores of this biome
American ________ is a Grassland Biome

18. Temperate Forest _____________ centimeters of rain per year
Dominated by broad-leaved hardwood trees that ____________________
Soil is rich and has lots of nutrients
Squirrels, mice, rabbits, deer and bears
Many animals will migrate in the winters

19. Tropical Rain Forests
Most Biologically diverse biome
Found around the Equator
More than __________ centimeters of rain a year
Warm temperatures
