What does the term biomagnification mean quizlet?
What is biomagnification? the concentration of toxins in an organism as a result of its ingesting other plants or animals in which the toxins are more widely disbursed.
When toxic or potentially toxic substances build up in the food chain the process is called?
In many cases, animals near the top of the food chain are most affected because of a process called biomagnification. Many of the most dangerous toxins settle to the seafloor and then are taken in by organisms that live or feed on bottom sediments.
Which of the following would be most affected by biological magnification of toxins?
Animals are most affected by biomagnification higher up the food chain after much accumulation.
How does bioaccumulation occur quizlet?
Bioaccumulation occurs when an organism absorbs a – possibly toxic – substance at a rate faster than that at which the substance is lost by catabolism and excretion.
What does biomagnification mean in biology?
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 does biomagnification factor represent?
Briefly, the BMF expresses the relative rise in concentration of a chemical from a prey to its predator, whereas the TMF represents the average value of the prey-to-predator magnification factor over a whole food chain or a segment thereof.
What happens during biomagnification?
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 are effects of biomagnification?
Biomagnification makes humans more prone to cancer, kidney problems, liver failure, birth defects, respiratory disorders, and heart diseases.
What is meant by biomagnification?
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. From: Treatise on Geochemistry, 2007.
What process does biomagnification describe?
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.
What is biomagnification known as?
Biomagnification, also known as bioamplification or biological magnification, is any concentration of a toxin, such as pesticides, in the tissues of tolerant organisms at successively higher levels in a food chain.
What happens biomagnification?
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.
What is biomagnification in simple words?
Biomagnification, or biological magnification, is the increasing buildup of toxic substances within organisms that happens at each stage of the food chain.
What causes biomagnification of toxins?
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 effect does biomagnification have?

What do you mean by biomagnification explain with an 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.
