Maximum DDT will occur in
Open in App
Solution
The correct option is D seagull
The correct option is (D)
Explanation of the correct option:
- Dichlorodiphenyltrichloroethane (DDT), chemically an organochlorine, is used as an insecticide.
- When released into the water through the agricultural run-off, it is ingested by the aquatic organisms like phytoplankton who are the main producers in an aquatic food chain.
- From thereon, DDT continues to rise up the food chain. And as successive consumers at the successive trophic level consume more food, it accumulates at the higher trophic level in greater amounts. This is called biomagnification.
- Seagulls are the top consumers in an aquatic food chain, thus they show the highest accumulation.
Final answer: Maximum DDT will occur in seagulls.
