Question

To control mosquitoes that help transmit malaria, swamps in malaria-infected regions were frequently sprayed with DDT. In one particular ecosystem, mosquitoes were eaten by mosquito fish, which in turn were eaten by kingfisher birds. If the mosquitoes had 0.2 ppm of DDT in their systems, what concentration of DDT would we expect to find in the kingfishers? (At each step of the food chain, the concentration would be expected to increase by about 10.)

Answer 1

20.0 ppm

Step-by-step explanation:

The concentration od DDT in the systems of kingfishers will be 20.0 ppm as it is increased 10 times.
