Image result for what role does seagrass play in the food chain
In addition to their ability to protect creatures from predators, seagrass fronds also serve as an important food source for marine life such as turtles and manatees, which graze on the leaves. ... An entire marine ecosystem, with a fully-functioning food chain, can emerge from a single bed of seagrass.
Answer:
Weight % of NH₃ in the aqueous waste = 2.001 %
Explanation:
The chemical equation for the reaction
Moles of HCl = Molarity × Volume
= 0.1039 × 31.89 mL × 
= 0.0033 mole
Total mass of original sample = 25.888 g + 73.464 g
= 99.352 g
Total HCl taken for assay = 
= 0.1083 g
Moles of NH₃ = 
= 0.03047 moles
Mass of NH₃ = number of moles × molar mass
Mass of NH₃ = 0.03047 moles × 17 g
Mass of NH₃ = 0.51799
Weight % of NH₃ = 
%
Weight % of NH₃ in the aqueous waste = 2.001 %
