Where do nutrients accumulate?

Stores

100
What form of carbon can be found in the atmosphere?
Carbon Dioxide
100
Can all plants take ammonium?
No
100

What is the breaking down of rocks?

Weathering

100
The process by which excess nutrients result in increased plant production and decay. Run off from precipitation also contributes to it.
Eutrophication
200
What are chemicals that are required for life processes?
Nutrients
200
What process converts carbon dioxide into sugars and water?
Photosynthesis
200

What process converts nitrogen gas into ammonium?

Nitrogen Fixation

200

Sedimentation will turn phosphate soil into what?

Phosphate rock

200
Give two examples of Human Activities that affect the Nutrient Cycle.
Can either be two if the following:?Land Clearing, agriculture, industry, mining, urban expansion, motorized transport, use of chemical fertilizers.

What is the continuous flow of nutrients in and out if stores?
Nutrient Cycle
300

What process converts sugars back into carbon dioxide?

Cellular Respiration

300
What process converts ammonium into nitrate?
Nitrification
300

How will trapped phosphorus in rocks be released?

By undergoing weathering.

300
Too much carbon dioxide will cause?
Global climate change
400

Where are carbon and nitrogen stores found?

In the atmosphere

400
Decomposition will turn dead carbon-containing plants and animals back into?
Carbon Dioxide
400
What process converts nitrate BACK into nitrogen gas?
Denitrification
400

Decomposition will turn dead phosphorus-containing plants and animals into what?

Phosphate soil

400
How do Human Activities create imbalance in the nutrient cycle?
By increasing the amount of nutrients.
500

The name of the cycle that contains living things and the cycling of non living things

Biogeochemical Cycles

500
Where do ocean currents carry cold ocean waters?
Warm Tropics
500
True or False: Decomposition will turn dead nitrogen-containing plants and animals back into NITROGEN GAS.
False. It will turn back into Ammonium.
500

What form does phosphorus take when in rocks? ?

Phosphate

500
How does too much phosphorus and nitrogen cause fish to die?
Too much phosphorus and nitrogen causes overproduction of algae that competes against fishes for food and oxygen.
