A pyramid of biological magnification in ground water has six concentration level of pollutant DDT (from bottom to top of the pyramid). The concentration of a pollutant i.e. DDT—represented by the orange dots. In the biological magnification pyramid these are labeled as:

1. Water with concentration level 1
2. Producer with concentration level 1,000
3. Zooplankton with concentration level 10,000
4. Small fish with concentration level 100,000
5. Large fish with concentration level 1,000,000
6. Fish eating birds with concentration level 10,000,000.
