Question

What is biological magnification? Will the levels of this magnification be different at different levels of the ecosystem?

Answer 1

Biological magnification is the phenomenon in which the concentration of harmful substances increases in living organisms with each successive trophic level.​ ​

• The levels of biological magnification are different at different levels of the ecosystem.
• It increases with each successive level.
• It is maximum at the highest trophic level, and minimum at the lowest trophic level. ​
• For example, it is the highest in humans, and the lowest in autotrophs like plants. ​ ​
