Biological magnification (or biomagnification) is the buildup of certain substances, such as DDT, in the bodies of organisms at higher trophic levels of food webs. DDT was once used extensively as an insecticide. DDT builds up in the fatty tissues of organisms.
Thanks everyone. If I understand correctly, magnification refers to the image size at the film plane which is the same regardless of whether the camera is 35mm or digital. The field of view depends on the focal length and the size of the negative or sensor. Therefore, a 100mm lens on a digital camera with a 1.5X crop factor will have the same field of view as a 150mm lens on a 35mm camera, but the two lenses will not produce the same magnification (at the film plane).
