Do marine organisms at higher trophic levels contain higher levels of mercury

1 answer:

5 0

Marine organisms at higher trophic levels will have higher concentrations than animals in lower trophic levels. This is because mercury is not easily eliminated from these organisms so the concentration can increase as you go up the food chain. For example, one fish eats five shrimp each with one molecule of mercury, the fish now contains five molecules. If a larger fish eats several fish with five molecules of mercury then the concentration increases through the trophic levels.

Of the molecules sif4 and sibr4, which has bonds that are more polar

eduard

<span>Of SiF4 and SiBr4, the atom SiF4 is more polar. This is because the cation of both molecules are Silicon, but the anions of each are different. In SiF4, the anion is Fluorine, which is more electronegative than the Bromine in SiBr4, which creates a larger dipole, which results in a more polar molecule.</span>
