Biomagnification is the accumulation of a chemical by an organism from water and food exposure that results in a concentration that is greater than would have resulted from water exposure only and thus greater than expected from equilibrium.

What is biomagnification and example?
Biomagnification is defined as the accumulation of a particular substance in the body of the organisms at different trophic levels of a food chain. One example of biomagnification is the accumulation of insecticide DDT which gets accumulated in zooplanktons. Small fishes consume these zooplanktons.
What is biological magnification class 10 science?
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 answer key?
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 an example of biological magnification?
Biological magnification refers to the process where toxic substances move up the food chain and become more concentrated at each level. An example of biological magnification and its dangers is any small fish that eats plankton that has been tainted with mercury.
What is biological amplification?
The accumulation and increase in concentration of chemicals, usually insecticides or their metabolites, in organisms at 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 the process of 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 is meant by biological magnification with the help of a food chain?
The increase in concentration of harmful chemical substances like pesticides in the body of living organisms at each trophic level of a food chain is called biological magnification.
What causes biological magnification?
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 biological magnification and what threat can it cause if any to us as humans?
This is biomagnification, and it means that higher-level predators-fish, birds, and marine mammals-build up greater and more dangerous amounts of toxic materials than animals lower on the food chain. In this activity you will explore the biomaginification of toxic chemical, mercury, through a simple marine food chain.
What is biological magnification What are its effect?
Biological magnification, or biomagnification, occurs when pollutants taken up by organisms at the base of the food chain reach high concentrations in the bodies of animals at the top of the food chain. Effects of biomagnification vary widely depending on the pollutant, organism and ecosystem in question.
