Q7. After exposure to a bioaccumulating toxin for long period of time, which type of organism would you expect

to have the highest toxin concentration?

O Fish

Zooplankton

Pitoplankton

All these would have about the same toxin concentration,

The correct answer is "Fish".

Explanation:

A bioaccumulating toxin will have its maximum concentration on species that live longer, because the toxin gradually accumulates into the organism. In this case, fish will have the highest toxin concentration because it lives longer than zooplankton or phytoplankton. Furthermore, fish is at a higher position in the food chain, therefore it will feed from other organisms that are potentially exposed to the toxin.
