1. The nutrients necessary for plant growth are found at very low concentrations in most natural waters. 

2. In the process of collecting nutrients, phytoplankton also collects certain human made chemicals such as some persistent pesticides. 

3. These may be present in the water at a very low concentrations that they cannot bemeasured even with a very sensitive instruments. 

4. The chemicals however, biologically accumulate in the organism and become concentrated at levels that are much higher in the living cells than in the open water. 

5. The small fish and zooplankton eat vast quantities of phytoplankton. 

6. In doing so, any toxic chemicals accumulated by the phytoplankton are further concentrated in the bodies of the animals that eat them. 

7. This is repeated at each step in the food chain. 

8. This process of increasing concentration through the food chain is known as biomagnification.
