9. DDT is a very effective pesticide, but was eventually banned in the U.S. due to concerns over its health impacts and the environmental problems it caused, particularly with birds of prey populations being reduced. Birds of prey are big birds that eat other birds, rodents and fish such as hawks, eagles, falcons and condors. The DDT would affect the birds of preys' eggs, making them thin and fragile and not able to survive nesting. DDT also impacts fish, smaller birds, and other species, but doesn't seem to have such dramatic effects on the smaller birds and plant-eating species as much as the big birds of prey. The fact that DDT seems to "target" birds of prey rather than others can be attributed to:

a. Birds of prey getting high levels of DDT in their diet due to eutrophication.

b. Birds of prey getting high levels of DDT in their diet due to biomagnification.

c. Birds of prey getting high concentrations of DDT in their diets due to bioaccumulation.

d. Birds of prey large physical body size makes them more vulnerable to DDT
