NEET BIOLOGY

Detailed explanation-1: -Two common groups that are known to biomagnify are chlorinated hydrocarbons, also known as organochlorines, and inorganic compounds like methylmercury or heavy metals. Both are lipophilic and not easily degraded.

Detailed explanation-2: -Explanation: Pollutants need to satisfy characteristics like long life, biologically active, soluble in fat etc. to make biomagnification possible. Biomagnification refers to a process of Biological Magnification, meaning the increase of contaminated substances/toxic chemicals that take place in the food chains.

Detailed explanation-3: -Synthetic (man-made) chemicals called Persistent Organic Pollutants, or POPs, are of primary concern when looking at bioaccumulation and biomagnification. These chemicals do not easily break down in the environment and can build up in the fatty tissues of living organisms.

Detailed explanation-4: -Biomagnification is the method of accruing toxic elements by different organisms within a food chain. A prominent example of it is the presence of mercury within predatory fish. This level is so high that consuming these can cause cancer.
