Cycling of Matter and Energy - 3

Question 1

exchange pool

Answer 1

Part of a cycle that holds an element or water for a short period of time

Question 2

reservoir

Answer 2

Part of a cycle that holds an element or water for a long period of time

Question 3

evaporation

Answer 3

Occurs when water on the surface changes to water vapor. some heats water and gives water molecules enough energy to escape into the atmosphere

Question 4

sublimation

Answer 4

occurs when ice and snow changed directly to water vapor. this also happens because of heat from Sun

Question 5

transpiration

Answer 5

Occurs when Plants release water Vapors through Leaf Force called stomata. the evaporation that occurs from the land surface along with transpiration is known as as evapotranspiration

Question 6

condensation

Answer 6

The process in which water vapor changes to Tiny droplets of liquid water

Question 7

precipitation

Answer 7

rain/snow/sleet/hail/freezing rain

Question 8

runoff

Answer 8

precipitation that falls on grounds surface

Question 9

infiltration

Answer 9

Precipitation that soaks into land becoming groundwater

Question 10

aquifer

Answer 10

Underground layer of rock that stores water, sometimes for thousands of years

Question 11

nitrogen fixation

Answer 11

Conversion of inert nitrogen to usable forms by special bacteria

hydrogen + nitrogen = ammonia (through bacteria)

nitrogen gas –> nitrate ions

Question 12

assimilation

Answer 12

uptake of nitrogenous compounds from soil by plants

Question 13

denitrification

Answer 13

conversion soil nitrates baxk to nitrigen gasses

Question 14

nitrification

Answer 14

conversion of amonia to nitrate and nitrates by bacteria

Question 15

ammonification

Answer 15

conversion of the nitrogen in the organic matter to ammonia by decomposers

nitogen –> ammonia (by decomposers)

planst and animals decompose, releasing nitrigen into the envoronment in the form of ammonium ions

Question 16

N-fixing bacteria

Answer 16

supplies plants w/ the vital nutrient that they can’t obtain from the air themselves

nitrogen (from air) –> ammonia in soil

Question 17

denitrifying bacteria

Answer 17

a group of bacteria that helps convert nitrates/nitrites into nitrogen-containing gases

Question 18

nitrifying bacteria

Answer 18

convert the most reduced from soil nitrogen, ammonia, intpo its most oxinized form, nitrate.

ammonia –> nitrate
