An area must meet 3 parameters, by law, to qualify as a

wetland.

TERM 4

Soil that lacks oxygen and allows only

hydrophytes to grow is called what?

DEFINITION 4

Hydric Soil

TERM 5

Why can wetland plants survive in wetlands?

DEFINITION 5

Hydrophytes can get oxygen to their roots, allowing them to

live in hydric soils.

How does water impact the formation of

wetlands?

Water reduces the amount of oxygen in the soil.

TERM 7

What gas does the bacteria in wetland soils

consume?

DEFINITION 7

Oxygen

TERM 8

What is the name of the wetland in which

shrubs are dominate?

DEFINITION 8

Scrub shrub wetlands are dominated by shrubs

TERM 9

What is another name for a forested

wetland?

DEFINITION 9

Swamp

TERM 10

What are three major causes of wetland loss

in the U.S?

DEFINITION 10

Drainage for agriculture Filling them in Development

How do levees contribute to the loss of

oxygen in the Chesapeake bay?

River waters are confined to the river channel The ability of

floodplains to take up nutrients is diminished nutrients are

transported to sensitive waters downstream

TERM 17

What can be determined by tree rings?

DEFINITION 17

Annual growth of the diameter of the tree during a growing

season How wet or dry the year was (they tend to be wider

during wet years and narrower during drought years)

Represent contributions to productivity for their ecosystems.

TERM 18

What does rising air

do?

DEFINITION 18

Rising air cools and condenses as it rises.

TERM 19

What is rising air associated with?

DEFINITION 19

Low pressure Fronts Windward sides of mountains

TERM 20

cloudy sky over Virginia?

DEFINITION 20

Low Pressure

sundog?

When viewing a sundog, you can see all of the colors of the

visible spectrum.

TERM 22

When does global circulation of air occur in

cells?

DEFINITION 22

When they are warm and rising When they are cool and

descending

TERM 23

Where is a desert likely to occur?

DEFINITION 23

A desert is likely to occur where global air circulation causes

air to descend because descending air tends to warm and

dry.

TERM 24

What is orographic precipitation?

DEFINITION 24

Orographic precipitation is when precipitation is caused by

collision with a mountain.

TERM 25

What does Shelford's Law of Tolerance

state?

DEFINITION 25

Shelford's Law of Tolerance states that every species tends

How can you define soil color?

DEFINITION 32

Chroma Value Hue

TERM 33

Why do wetlands tend to have higher organic

matter content in their soils?

DEFINITION 33

decomposition rates. Saturated soils allow for less oxygen for

bacteria

TERM 34

table to look like for mottling to occur?

DEFINITION 34

For mottling to occur, the water table depth will vary greatly

and have some spikes as well as some lows.

DEFINITION 35

Glycolysis then Kreb's Cycle (citric acid cycle) then

Chemiosmotic Process (oxidative phosphorylation)

How are hydrogen molecules transported

prior to cell respiration?

They are transported as part of a glucose molecule.

TERM 37

Why is oxygen critical during cell respiration?

DEFINITION 37

Oxygen bonds with hydrogen to maintain the Hydrogen

gradient that is necessary to keep the flow of Hydrogen

atoms moving.

TERM 38

What processes can the absence of oxygen

stop?

DEFINITION 38

Kreb's Cycle and Chemiosmostic Proces

TERM 39

Why is the respiratory, digestive, and

circulatory systems important to cell

respiration?

DEFINITION 39

Getting Oxygen to cells Eliminating wast products like CO

Getting glucose to cells

TERM 40

How do fish maintain the concentration

gradient b/n the amount of O2 in the water

and the amount of O2 in their blood?

DEFINITION 40

Fish maintain this because of the direction that the blood and

water flow.
