Figure 9

Translocation and uptake of nitrate by above-ground and below-ground biomass of Zostera nigricaulis at Blairgowrie, Swan Bay and Kirk Point in Port Phillip Bay. Percentage translocation is the amount of nitrate translocated to the above-ground or below-ground biomass, calculated as a percentage of the total nitrate assimilated by the seagrass. The arrows in the figure depict the movement of ammonium from one compartment to the other.
