Question

In a food chain consisting of toxic soil, toxic grasses, rabbits that eat the toxic grass, and hawks 

that eat the rabbits, the highest concentrations of toxins would occur in the 

  1. A) soils. 
  2. B) tissues of the hawks. C) tissues of the grasses. 
  3. D) tissues of the rabbits. 



Expert Solution
Step 1

In a food chain consisting of toxic soil, toxic grasses, rabbits that eat the toxic grass, and hawks that eat the rabbits, the highest concentrations of toxins would occur in the soils. Because the toxin in the soil that will be derived from an outer source in the large amount. So they are influenced in absorbing these toxins to the tissue of grass. There will be a limit in taking the toxins by the tissue of grass. Much intake of toxins will lead to damaging the grass. So the number of toxins in the grass will be lesser than the soils.

These toxic grass will be taken by the rabbits. Also, the toxin present in the grass will move to the rabbit tissues. But the number of toxins will be in lesser amounts. 

When these rabbits that contain toxic tissues will be eaten by the hawk and also the toxin transferred to hawks. But the number of toxins present in the hawk tissue will be less than soils.
