According to this diagram, plants absorb
nitrates
nitrogen fixing bacteria

This is NOT a part of the phosphorus cycle.
Phosphate is incorporated into sedimentary rocks
Phosphate bound to soil
Atmospheric phosphate
Phosphate is absorbed from the soil by plants
_____ brings phosphorous into our waterways. .
Precipitation
Runoff
Transpiration
Condensation
This is released by the weathering of rocks.
Carbonate
Phosphate
Phosphorus
Nitrogen
Too much phosphorus in waterways (rivers, lakes) can lead to___________.
eutrophication
nothing
decreased pH levels
diseases
How does eutrophication cause the death of aquatic organisms
the build up of carbon dioxide in the water
the lack of nitrogen in the water
the lack of carbon dioxide in the water
the lack of oxygen in the water
The two critical nutrients in eutrophication are... (select two)
nitrates
phosphates
carbon dioxide
dissolved oxygen
In eutrophication, dissolved oxygen levels decrease because
bacteria use it as they decompose organic material
algae uses it during photosynthesis
it reacts with hydrogen to form H2O (water)
fish use it up as they consume algae
What effect does the sun have on surface water?
It causes it to boil
It causes it to rain
It causes it to sink
It causes it to evaporate
When water vapor is cooled and forms droplets of liquid water
Condensation
Evaporation
Transpiration
Runoff
What is precipitation?
Sweat from our bodies on hot days
Warm rain but not cold snow or sleet
Gas that we use in furnaces or ovens
Any form of water that falls from the sky

precipitation
evaporation
transpiration
condensation
____________________ is the process by which water on the ground surface enters the soil. ________________ rate in soil science is a measure of the rate at which soil is able to absorb rainfall or irrigation.
Infiltration
Percolation
Deposition
Condensation
The process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers.
water cycle
evaporation
evapotranspiration
precipitation
