Water and Aquatic Biomes

2. What is required in order to regulate something?
Energy
What is one of the main things organisms must regulate?
Water

3. What raw materials are needed for photosynthesis?
Water and carbon dioxide (+ energy from the sun)
What begins every food chain?
Producers (autotrophs)

4. Sunlight =
Photosynthesis =
Energy for life =
Producers =
Consumers =
More light…..more…..
Life

5. How large are aquatic biomes?
Cover 75% of the earth’s surface
What effect to aquatic biomes have on ecology?
Responsible for rainfall and temperature regulation
Help with oxygen production and carbon dioxide consumption

6. What is the photic zone of the ocean?
The upper region that has light penetration
Red light penetrates deeper, since it has longer wavelengths

7. What is the aphotic zone?
The lower region of the ocean, where no light penetrates

8. What is the benthic zone of the ocean?
The very bottom of the ocean
Organisms at the bottom tend to be decomposers or waste feeders (detritis)
No photosynthesis occurs here, but some organisms can carry on chemosynthesis

9. What is the abyss of the ocean?
The very deepest parts of the ocean, such as the deep sea trenches

10. What is the pelagic zone of the ocean?
From the surface to the bottom in the mid-region of the ocean

11. What is the thermocline?
The temperature gradients in the body of water

12. In fresh water what is the littoral zone?
The shallow water where light is present for plants

13. In fresh water, what is the limnetic zone?
The middle surface region, where phytoplankton and zooplankton live and produce

14. In freshwater, what is the profundal zone?
The deep middle region where most fish are found

15. In freshwater, what is the benthic zone?
The bottom of the water, with less light penetration

16. In freshwater, what is the pelagic zone?
From surface to bottom in the mid-range

17. What is an oligiotrophic type of lake?
Nutrient poor, very deep, cold
Appears clear, no phytoplankton
Few plants or animals in water

18. What is a eutrophic lake?
It is nutrient rich, fairly shallow and warm
Appears murky, with lots of plants and animals

19. What is a mesotrophic type of lake?
An in between condition, with a moderate number of plants and animals present

20. What are headwaters in a stream or river?
Located high in mountains
Cold, clear, fast, narrow, nutrient poor, high dissolved oxygen content
Support fish that need lots of oxygen, like trout

21. What is a midstream river or stream?
Between the mountains an coast
Warm, slow, wide, nutrient rich, murky
Not as much dissolved oxygen
Not as many plants and animals
Catfish would be more adapted

22. What is an estuary?
Where fresh water meets salt water
The Bay of Mobile or any bay
Very nutrient rich
Water almost black
Lots of biodiversity

23. What are wetlands?
Lands that have lots of water and plants that live above water
What are two types of wetlands?
Swamps
Marshes

24. What is a swamp?
Has trees

25. What is a marsh?
Has reed grasses only

26. In a marine biome, what is the intertidal zone?
Very harsh environment
Where tides move in and out
Rich in biodiversity
Plenty of light for photosynthesis

27. In a marine biome, what is the neritic zone?
From shore to the continental shelf drop off
Rich in biodiversity
Plenty of light

28. In marine biomes, what is the oceanic pelagic?
Photoic and a photic zones
Lacks biodiversity
Has lots of large fish

29. In marine biomes, what is the coral reef?
Very rich in biodiversity
Rainforest of the ocean
Are endangered and protected by low
Warm water climates

30. In marine biomes, what is the benthic zone?
Deep sea thermal vents
Mid ocean rift valleys
Moderate biodiversity
