When living organisms obtain water and food from their environment, they may also take in toxic pesticides.

The data table below shows the concentrations of a pesticide in tissues of organisms at different levels of a food chain. What does this information suggest to a person who is concerned about health and is deciding on whether to have a plant-rich or animal-rich diet? Support your answer using the information provided.
