Go to the following website to answer the questions below: http://fc.deltasd.bc.ca/~mannandale/sc10/hw/EP_phosphorus_cycle.swf
1. Fill out all the missing information on the Phosphorus Cycle diagram provided.
2. Using your phoshorus cycle diagram, answer the following questions:
a. What are the two most abundant phosphate stores? How many megatonnes is stored in
each?
b. How much mineable phosphate is there? (in megatonnes)
c. Describe two ways that phosphate could move from the deep stores in the Earth’s crust and
ocean sediments and get into soils so that it is available for uptake by plants (terrestrial
organisms)?
