Current Question (ID: 17883)

Question:

$\text{If a lake is contaminated with DDT, its highest concentration would be found in:}$ $1.\ \text{Primary consumer}$ $2.\ \text{Secondary consumer}$ $3.\ \text{Tertiary consumer}$ $4.\ \text{None of the above.}$

Options:

1. $\text{Primary consumer}$
2. $\text{Secondary consumer}$
3. $\text{Tertiary consumer}$
4. $\text{None of the above.}$

Solution:

$\text{DDT is a pesticide.}$ $\text{If a lake is polluted with pesticides, large fish will contain the maximum amount of pesticide.}$ $\text{The process due to which large fish will contain the maximum amount of pesticide is called biological magnification.}$ $\text{It is also called as biomagnification.}$ $\text{Phytoplanktons and zooplanktons absorb pesticide from the polluted water.}$ $\text{Small fishes eat phytoplankton and zooplanktons.}$ $\text{There will be increased accumulation of pesticide in their bodies.}$ $\text{These small fishes are eaten by big fish.}$ $\text{Hence, the big fish will have the maximum amount of pesticide called tertiary consumer.}$ $\text{Thus, the correct answer is 3.}$
