5

Reservoirs

Places where water is stored for some period of time

6

Hydrologic cycle

Exchanges water along reservoirs

7

What powers the hydrologic cycle?

Solar energy

8

Turnover time

Time required for the entire volume of a particular reservoir to be renewed

9

Aquatic environment biology corresponds to variations in:

Light
Temperature
Water movement
And chemical factors

10

To live in water. Animals need to

Use gills

Store oxygen for long time

Transport oxygen to tissues

11

Water flows from

Areas of low solute concentrations to those of higher solute concentration

12

Oceans

Largest aquatic environments on the plant that occupy 70% of earths surface

13

5 oceans

Arctic
Atlantic
Indian
Pacific
Southern

14

Oceans can be divided into

Horizontal and vertical zones

15

Horizontal zone

Littoral zone

Neritic zone

Oceanic zone

16

Littoral zone

Shallow shoreline affected by tides

17

Neritic zone

From coast to the margin of the continental shelf

18

Oceanic zone

Beyond neritic

19

Photosynthesis dependant organisms (photic zone)

Phytoplankton

20

Zooplankton

Barrier reefs

Stand between open sea and lagoon

26

Atolls

Dot the tropical oceans

27

Physical conditions

Light

Light penetration allows support for photosynthesis

28

Temperature for kelp

10 to 20 degrees

29

River basin

Area of a continent that is drained by a river drainage network

30

Rivers usually

Flow out to a sea or interior basin

31

35

Wetland habitats come in two forms _____+______

Peat and those that do not

36

Non pest forming wetlands

include costal marshes and mangroves

37

Peat

Consists partially of decomposed plant material

38

Two types of peats

Bogs and fens

39

Bogs

Found in landscape depressions

Precipitation is the only source of water

40

Fens

Typically flat due to high water levels
