As DDT passes into food chain, the concentration:
Open in App
Solution
The correct option is A Increases
- DDT (Dichlorodiphenyltrichloroethane) is an organochlorinated compound that is stable in nature. The level of DDT increases as the food chain progresses.
- It means, the primary consumers will have more DDT concentration than the producers, the secondary consumers will have more than primary consumers and so on.
- The highest concentrations will be seen in the top carnivore. As the consumers at each successive trophic level consume more food to fulfil their energy requirements.
- Therefore, DDT accumulates in higher concentrations in successive trophic levels. This process is called biomagnification.
Hence, the correct answer is 'Increases'.
