Pollutants often bioaccumulate in organisms at lower trophic levels, but they can also become diluted as they move up the food chain. While some pollutants, particularly persistent organic pollutants, can biomagnify and increase in concentration at higher trophic levels, this is not the case for all pollutants. Additionally, energy transfer between trophic levels is inefficient, leading to fewer organisms at higher levels, which can limit the overall concentration of pollutants. Environmental processes, such as degradation and dilution, also help mitigate pollutant accumulation at higher trophic levels.
