What is the original, and primary reservoir of inorganic phosphate (PO43-)in terrestrial ecosystems?
live plants and animals
groundwater
the atmosphere
rocks
Nitrogen and carbon are cycled on a global scale. Why does phosphorus cycling tend to occur more locally?
it primarily involves the weather of rocks, which are mostly stationary
it only involves land animals that cannot swim across oceans to transport the nutrient
it occurs in areas where cloud formation is low, so it rarely gets trapped in water vapors
all of the answers are correct
The phosphorus cycle occurs much more quickly than the carbon and nitrogen cycles.
true
false
Phosphorus enters the P cycle as
atmospheric phosphate
diphosphorus
rock phosphate
organic phosphate
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
Too much phosphorus in waterways (rivers, lakes) can lead to___________.
eutrophication
Nothing
Death
diseases
In general, algal blooms occur when
toxins accumulate in shellfish.
nutrients decrease in the water.
nutrients increase in the water.
