Unit 1 APES

Question 1

Biome

Answer 1

An area that shares an average yearly temperature and precipitation pattern

Question 2

Reservoir

Answer 2

things that temporarily store matter

Question 3

Source

Answer 3

processes that move matter around between reservoirs

Question 4

Sink

Answer 4

reservoirs that store matter than they give off

Question 5

Carbon source

Answer 5

return carbon to the atmosphere

Question 6

carbon sink

Answer 6

remove carbon from the atmosphere, storing more carbon than they release

Question 7

nitrogen fixation

Answer 7

process of N2 gas from the atmosphere being converted into biologically available nitrogen such as ammonia (NH3) or nitrate (NO3)

Question 8

assimilation

Answer 8

plants taking in nitrogen from the soil or animals taking in nitrogen by eating plants

Question 9

ammonification

Answer 9

soil microbes or bacteria converting organic matter/waste into ammonium (NH4)/ ammonia (NH3)

Question 10

nitrification

Answer 10

soil bacteria converting into ammonium(NH4), into nitrate (NO3)

Question 11

dentrification

Answer 11

soil bacteria converting NO3/NO2 into N2O/N2 gas

Question 12

evaporation

Answer 12

sunlight hits liquid water, heating it into a vapor that enters the atmosphere

Question 13

precipitation

Answer 13

water vapor in the atmosphere condenses as the air cools due to its increased elevation away from the warmth of earth’s surface (from solar radiation) and falls as rain/snow

Question 14

primary productivity

Answer 14

RATE at which plants/producers in an area convert sunlight into glucose or other biological molecules
