Difference b/t biounlimited, biointermediate, and biolimiting nutrients?
Conservative or nonconservative? Variation throughout ocean?
Biounlimited - conservative - concentrations are not significantly affected by chemical/biological reactions; little or no variation throughout oceans, constant ratio to Cl- throughout oceans.
Biointermediate - nonconservative (slightly affected by chem/bio rxns) Are usually present in sufficient concentrations to not limit primary production, slight variations throughout oceans
Biolimited - nonconservative (significantly affected by chem/bio rxns), large variations throughout ocean, highly depleted in surface waters --> limit primary production.
