CBSE Class 10 Answered
If it is uncertain about how much food the organisms at higher trophic levels will eat, then why is it certain that the toxicity will increase as the trophic levels increase? (in reference to my previous question)

Expert Answer
The intensity of accumulation of the toxic substance increases as we move from a lower trophic level to a higher trophic level in a food chain. This phenomenon is called biomagnification. This occurs when an organism absorbs a toxic substance at a rate greater than the rate at which the substance is lost from the food chain.
