What is DDT in food chain?
When an animal consumes food having DDT residue, the DDT accumulates in the tissue of the animal by a process called bioaccumulation. The higher an animal is on the food chain (e.g. tertiary consumer such as seals), the greater the concentration of DDT in their body as a result of a process called biomagnification.
Can you still buy DDT?

This can result in a rapid decline in relative effectiveness of the pesticide.
