- Synopsis
- This is a labelled pyramid diagram showing how a pesticide becomes more concentrated in the bodies of animals further along the food chain. There is a locator dot shown, which will be at the top left of the page when the image is the correct way up. The population of each animal is represented by a rectangle. Earthworms, with the largest population are at the bottom of the page. The earthworm's predator, the blackbird, is up the page from this and the blackbird's predator, the peregrine falcon which has the smallest population, is at the top of the pyramid in the centre of the page. Each dose of DDT is represented by a solid dot (red in the Large Print version).
