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.

What is biological magnification with Example Class 10?
Answer: Biological magnification is a phenomenon that expalins the increase in the concentration of harmful chemicals like pesticides and fertilisers in each trophic level. As these chemicals are not degradable, the organisms in soil and water can accumulate them in their bodies.
What is biological magnification explain it?
Biological magnification, or biomagnification, is the increasing buildup of toxic substances within organisms that happens at each stage of the food chain. The buildup of toxic substances within a single organism is called biological accumulation.
What is biological magnification answers?
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.
What is biological magnification Class 8?
The process by which the harmful and toxic substances enter the food chain and get concentrated in the body of living organisms at each successive level in food chain is called biological magnification.
What is biological magnification quizlet?
Biological Magnification. the increase in concentration of substances along the food chain. Also known as Bioaccumulation. Biological Magnification Result. Organisms at higher levels of food chain more at risk and suffer greater than those organisms lower in the food chain.
What is meant by magnification Class 10?
Magnification is defined as the enlargement of the image formed by a mirror, whether it is a concave mirror or a convex mirror, relative to the size of the object. The mirror which can give an erect and enlarged image of an object is a concave mirror.
What is an example of bioaccumulation?
Mercury contamination is a good example of the bioaccumulation process. Typically, mercury (or a chemical version called methylmercury) is taken up by bacteria and phytoplankton. The result can be the build up (biomagnification) of large concentrations of mercury in human and animal tissue.
What is biological magnification and give its causes?
The increased concentration of chemicals at any trophic level is called biological magnification. It occurs due to the excessive use of pesticides which enter our food chain.
What happens biological magnification?
Biomagnification is the process by which toxic chemicals build up within predators. This typically occurs across an entire food chain and affects all of the organisms but animals higher up in the chain are more impacted. Therefore, when the food chain progresses, concentrations increase or magnify.
What are examples of compounds that Biomagnify?
Examples of compounds that biomagnify
- Organic compounds.
- DDT (Dichlorodiphenyltrichloroethane, or Dichloro Diphenyl Trichloroethane)
- β-Methylamino-L-alanine (BMAA)
- HCB (Hexachlorobenzene)
- Heavy metals (such as mercury, lead, chromium)
- PCBs (Polychlorinated Biphenyls)
What are some examples of substances chemicals that are Bioaccumulated by organisms?
Examples of bioaccumulating substances are e.g. halogenated hydrocarbons such as polychlorinated biphenyls, brominated flame retardants, perfluorinated compounds, polyaromatic hydrocarbons.
What is biological magnification explain biological magnification of DDT?
Biomagnification happens when toxic chemicals, like DDT, whose remains in the environment are consumed indirectly by organisms through food. When an organism in the higher food chain consumes the lower organism containing such chemicals, the chemicals can get accumulated in the higher organism.
What is biomagnification 12th?
Biomagnification or biological magnification is a gradual increase in the concentration of toxicants at successive trophic levels. This happens because a toxic substance accumulated is not metabolised or excreted by the organism and is passed on to the next higher trophic level.
