Match each action to its stage in the phosphorous cycle.
Microbial action breaks down decaying
biomass into organic compounds.
Water percolates through the soll and
carries away nutrients in runoff that
eventually reaches groundwater.
Organic sediment on lake bottoms and
ocean floors is broken down into
inorganic compounds.
Water reacts with sedimentary rock
and produces soluble phosphate.
