Question 20

Carbon Source

Answer 20

a process that adds carbon to the atmosphere

Question 21

Carbon Sink

Answer 21

carbon reservoir that stores more carbon than it releases

Question 22

Short-term carbon reservoir

Answer 22

vegetation

Question 23

Long-term carbon reservoir

Answer 23

rocks

Question 24

Photosynthesis

Answer 24

takes in carbon to plants/trees and emits oxygen

Question 25

Cellular Respiration

Answer 25

takes in oxygen and releases carbon

Question 26

Fossil Fuel Combustion

Answer 26

emits carbon as gas after mixing with oxygen and is added into the atmosphere

Question 27

How long does nitrogen stay in reservoirs?

Answer 27

Nitrogen stays in reservoirs for shorter periods of time than carbon

Question 28

Nitrogen Fixation

Answer 28

process of N2 gas being converted to NH3 (ammonia) or NO3 (nitrates)

Question 29

How do organisms take in nitrogen?

Answer 29

Plants take in NO3 (nitrate) or NH3 (ammonia) from roots in soil; animals take in nitrogen by eating plants

Question 30

Largest Nitrogen Reservoir

Answer 30

Atmosphere!

Question 31

Anthropogenic ways nitrogen cycle is altered:

Answer 31

Synthetic Fertilizer - nitrates in fertilizer can leach out of the soil and to nearby waterways that lead to bodies of water, which causes algae blooms that block sun

Question 32

Phosphorus Sources

Answer 32

weathering & mining

Question 33

Phosphorus sinks

Answer 33

rocks and sediments

Question 34

Major Phosphorus Reservoir

Answer 34

sediment!

Question 35

Weathering

Answer 35

rain & wind breaking down rocks, and he phosphate inside dissolves in the nearby waterways which carry it to nearby soil + bodies of water

Question 36

Why is the phosphorus cycle much slower?

Answer 36

The phosphorus cycle runs a lot slower than other cycles because there is not atmospheric
