the soil is saturated

Question 4

terrestrial,
ecosystems in their natural
rain usually hits the

Answer 4

leaves and other surfaces of plants before it reaches the soil

Question 5

If water is not taken up by plant roots, it may

Answer 5

percolate down into the subsoil and bedrock,
forming groundwater

Question 5

Groundwater is water found in the

pores between particles in sand and gravel or in the
cracks in rocks

Question 5

groundwater is

Answer 5

an important reservoir of
freshwater.

Aquifers

Answer 5

groundwater reservoirs

Question 5

many aquifers are being used up

Answer 5

faster than
they’re renewed by water that moves down from
above

Question 5

They hydrologic cycle can
help cycle elements
(nutrients)

Answer 5

through the
environment

Question 5

hydrologic cycle

Answer 5

important in moving elements from terrestrial to aquatic ecosystems

Question 6

Nutrient cycling

Answer 6

use, transformation, movement, and reuse of nutrients.

Question 7

Energy makes

Answer 7

one-way trip through
ecosystems.

Question 8

The path atoms take from the living (biotic) to the non-living
(abiotic) world and back again is called a

Answer 8

biogeochemical
cycle

Question 9

there are 50 - 70 elements

Answer 9

found in living organisms

Question 10

Storage in

Answer 10

nutrient pools or compartments

Question 11

Movement, or nutrient flux,

Answer 11

between pools in
an ecosystem

Question 12

Nutrient sink

Answer 12

absorbs a nutrient faster than
releasing it.

Question 13

Nutrient source

Answer 13

releases nutrient faster than it is absorbed

Question 14

The carbon cycle

Answer 14

Rapid carbon exchange
between living organisms, Long-term cycling of carbon through geologic processes

Question 15

how much of our body is carbon

Answer 15

~18%

Question 16

Carbon exists in the air largely as

Answer 16

carbon dioxide

Question 17

Cellular respiration converts the organic carbon

Answer 17

back into CO2 gas

Question 18

Mineralization

Answer 18

Conversion from organic to inorganic form

Question 19

mineralization occurs

Answer 19

primarily during decomposition

Question 20

Geologic processes in the C cycle

Answer 20

happen much more slowly

Question 21

Carbon-containing sediments in the
ocean floor are taken deep within the
Earth in a process called

Answer 21

subduction, in
which one tectonic plate moves under
another

Question 22

Increased atmospheric CO2

Answer 22

is directly correlated with
increased annual mean
temperatures globally

Question 23

Nitrogen is a key component

Answer 23

of the bodies of
living organisms.

into a useable
form

Question 26

Phosphorus is often the

Answer 26

limiting nutrient in aquatic ecosystems

Question 27

Eutrophication

Answer 27

a process by which
excess nutrients in aquatic ecosystems feed biological
productivity

Question 28

Eutrophication

Answer 28

LOWERS OXYGEN IN WATER, MAKING DEAD ZONES
