You are correct.
| Sadly enough, the use of pesticides such
as DDT (dichlorodiphenyltrichloroethane) and dieldrin are
directly related to the peregrine's decline. Residues (what
is left after the chemical breaks down) can stay in the environment
for many years and are passed along the food chain. High residue
levels in the peregrine resulted in abnormal breeding behaviour,
thin eggshells and dead embryos (an animal at any stage of
development before birth or hatching) within the egg. |
Go to question 8.
