Question

15) Which of the following possess the highest biological magnification: [1]
Grasshopper; frog, snake and peacock.​

Answer 1

Answer:

snake is the correct answer

Answer 2

The highest biological magnification is possessed by the Peacock.

• The amount of DDT present is higher in the higher organisms.
• The Grasshopper contains DDT comparatively less, when it is eaten by a Frog it multiplies and becomes more in quantity.
• The Frog when eaten by a Snake again multiplies the amount of DDT present.
• The Snake when eaten by a Peacock doubles the amount of DDT present in it.
• Now the highest concentration of DDT will be found in Peacock.

Hence, the Peacock possesses the highest biological magnification in this case.
