The carbon, oxygen, nitrogen and phosphorous cycle

Question 1

In the carbon cycle, it cycles rapidly. Carbon moves from.. producers to..

Answer 1

consumers & decomposers and back to the atmosphere

Question 2

In the carbon cycle, forest fires, decomposition and cellular respiration releases..

Answer 2

carbon into the atmosphere

Question 3

In the carbon cycle, the slow cycling part of it is when carbon is gathered and is stored in various reservoirs for long periods of time. Thus leading it to be..

Answer 3

unavailable to organisms until it is released

Question 4

In the carbon cycle, the ocean is the largest..

Answer 4

carbon sink (dissolves CO2)

Question 5

Organic living carbon sinks / reservoirs..

Answer 5

Bogs, trees, fossil fuel deposits

Question 6

inorganic carbon sinks / reservoirs..

Answer 6

atmosphere, ocean, earth’s crust, sedimentary rock

Question 7

In the carbon cycle, carbon can be released both..

Answer 7

quickly (forest fires) and slowly (weathering) through natural process

Question 8

In the carbon cycle, trees store large amounts of carbon, therefore deforestation and forest fires releases..

Answer 8

large amounts of carbon

Question 9

The 2 process of the carbon cycle..

Answer 9

Fixing Carbon and releasing Carbon

Question 10

In the carbon cycle, the process of fixing Carbon (which is converting gas to solids) involves dissolving CO2 to water –> makes carbonates –> which then makes calcium carbonate (found in shells and forms of ocean sediment) –> which turns in to rocks when..

Answer 10

crushed and heated

Question 11

in the carbon cycle, fixing carbon can also occur in..

Answer 11

photosynthesis

Question 12

in the carbon cycle, the carbon is released when rocks broken down by volcanos, by rotting, decomposing..

Answer 12

organisms, combustion of fossil fuels and cellular respiration (all these releases carbon)

Question 13

uses of carbon, carbon becomes..

Answer 13

coal (fossil fuels)

Question 14

Uses of carbon, carbon makes up all organisms and is used to make..

Answer 14

sugars (glucose), lipids, proteins, cell membranes

Question 15

uses of carbon, carbon makes calcium carbonate which are ocean..

Answer 15

shells

Question 16

In the oxygen cycle, the process of the oxygen cycle is..

Answer 16

photosynthesis and cellular respiration

Question 17

in the oxygen cycle, the use is..

Answer 17

breathing, sugar (glucose), found in all organisms, atmosphere

Question 18

The reservoirs of the oxygen cycle..

Answer 18

Atmosphere, rocks on land, ocean (dissolve CO2 in ocean plants like seaweed and produce oxygen in the ocean)

Question 19

in the nitrogen cycle, nitrogen makes up how much of the atmosphere?

Answer 19

78% of the atmosphere

Question 20

in the nitrogen cycle, organisms can not use atmosphere..

Answer 20

nitrogen

Question 21

in the nitrogen cycle, there are 3 processes and they are..

Answer 21

Nitrogen fixation, ammonification and denitrification

Question 22

in nitrogen fixation (a process of the nitrogen cycle), bacteria found in soil or roots of legumes convert atmospheric nitrogen into..

Answer 22

ammonium (NH4)

Other bacteria found in the soil convert NH4 to NO3 (nitrification)

Question 23

in nitrogen fixation (a process of the nitrogen cycle), lightning can also convert N2..

Answer 23

to NO3

Question 24

in ammonification (a process of the nitrogen cycle), detritus (dead or waste) is decompose and NH4 is released..

Answer 24

back into the soil

Question 25

in ammonification (a process of the nitrogen cycle), most NH4 is used by bacteria and is converted into NO2 then into..

Answer 25

NO3 which is what plants use for protein

Question 26

Denitrification (a process of the nitrogen cycle), some bacteria use the oxygen from NO3, the N2 is returned back to..

Answer 26

the atmosphere
