Nutrient cycling

Question 1

** nutrient pool*

Answer 1

Amount of a paticular nutrient stored in a portion of an ecosystem(nutrient thats dense in a particular erea)

Question 2

** nutrient flux**

Answer 2

Moving nutrients between the pools of an ecosystem

Question 3

nutrient cycle

Answer 3

The storage of chemical elements in nutrient pols and the flux (transfer) between pools

Question 4

nutrient sink

Answer 4

Part of biosphere where particular nutrients is absorbed faster than it is released

Question 5

nutreient source

Answer 5

Portion of the biosphere where a particular nutrients is released faster than it is absorbed

Question 6

Phosphorus cycle

Answer 6

Assential to life processes

Not a lot comapred to nitrogen

In rocks(marine sediment)

(Bc of rocks) theres lots in soil but not in the form usaeble to plants or microbes

Question 7

Nitrogen cycle

Answer 7

Used in structure and function

Pool in the atmosphere

Few organisms can use N2

Question 8

ammonification

Answer 8

Bacteria and fungi decompose organic N in tissues and conver to ammonium

Question 9

nitrification

Answer 9

Bacteria convert ammoinum to nitrate

Question 10

denitrification

Answer 10

Bacteria convert nictrate back to N2

Question 11

immobilization

Answer 11

Bacteria take up inorganic N and convert it into organic (in their cells)

Question 12

Carbon cycle

Answer 12

Organic part of organic molecules

Moves betwwen organisms and atmosphere by photosysnthesis and respiration

Either cycles rapidly or pools for a long time

Question 13

succession

Answer 13

Change in plant, animals and microbrial communites in an area following disturbance or the creation of new substrate

Question 14

primary succession

Answer 14

Sucession that occurs on newly exposed geological substrates, not modified by organisms (the creation of soil)

Question 15

Secondary succession

Answer 15

Succession that occurs in areas where disturbance destroys community without destroying the soil(disturbance of cummunity where there was already soil)

Question 16

pioneer community

Answer 16

First plant to colonize succession
