In higher tropic level or top of the food chain the organism are most affected by biomagnification.
Biological magnification is the process by which the level of concentration of toxic compound increases and accumulates along a food chain into higher levels while eutrophication is the process by which the excessive growth of algae occurs due to release of nutrients including nitrates and phosphates into water bodies …
Hint: The trophic level is the step or level included in a food chain. It denotes the number of steps the organism is from the start of the chain. … There are 4 trophic levels it includes producers, herbivores (primary consumers), carnivores (secondary consumers), predators (tertiary consumers).
The process of accumulating toxic chemicals such as pollutants, pesticides and other toxins directly into the human body either through air, water, food intake, or directly through the skin is termed as Bioaccumulation.
Answer: BIOLOGICAL MAGNIFICATION OR BIOMAGNIFICATION IS DEFINED AS THE INCREASE IN THE CONCENTRATION OF THE TOXICANTS AT SUCCESSIVE TROPHIC LEVELS. Actually, the toxic substances can neither be excreted nor metabolised , hence, they get accumulated in an organism and thus, are passed on to higher trophic levels.
Bioaccumulation. The gradual build-up of chemicals in living organisms. Biomagnification. The process in which chemicals not only accumulate but become more concentrated at each trophic level.
biomagnification – increase in concentration with increase of in trophic levels, e.g. DDT.
Predatory fish – fish that eat other fish that have eaten still other fish and animals – will have some of the highest concentrations of biomagnified chemicals. Many popular fish are also rich in fat and fish oils, which is where many toxins are stored.
