biomagnification (noun) · biomagnifications (plural noun)
1. : the process by which a compound (such as a pollutant or pesticide) increases its concentration in the tissues of organisms as it travels up the food chain In a process known as Biomagnification, fish accumulate mercury more rapidly than they excrete it, and every fish up the aquatic food chain contains more than the one it just ate.

11. Biomagnification refers to the condition where the chemical concentration in an organism exceeds the concentration of its food when the major exposure route occurs from the organism’s diet.
12. Biomagnification results from the process of bioaccumulation and biotransfer in which the tissue concentration increases in organisms higher up the food chain as a result of predation (see Figure 5)
13. Biomagnification (or bioaccumulation) refers to the ability of living organisms to accumulate certain chemicals to a concentration larger than that occurring in their inorganic, non-living environment, or in the case of animals, in the food that they eat
14. Biomagnification is also known as “ biological accumulation ” refers to the process by which certain toxic substances such as mercury and pesticides find their way into the environment like water bodies and gradually move up the food chain in much higher concentrations.
15. Biomagnification, or biological magnification, is the increasing buildup of toxic substances within organisms that happens at each stage of the food chain.
16. Students read about bioaccumulation and Biomagnification, then position themselves as part of the ocean food web
17. Finally, they draw a food web for a specific marine ecosystem that illustrates Biomagnification …

20. Biomagnification The result of bioaccumulation and biotransfer by which tissue concentrations of chemicals in organisms at one trophic level exceed tissue concentrations in organisms at the next lower trophic level in a food chain.
21. 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
22. Biomagnification should not be confused with bioaccumulation
23. While Biomagnification refers to increasing concentration of substances with each successive link in the food chain, bioaccumulation is the increase in the concentration of a particular substance within an organism.
24. Biomagnification is a cumulative increase in the concentrations of a persistent substance (e.g
25. Bioaccumulation and Biomagnification are two different processes that often occur in tandem with one another.Bioaccumulation is the process by which toxins enter the food web by building up in individual organisms, while Biomagnification is the process by which toxins are passed from one trophic level to the next (and thereby increase in concentration) within a food web.
26. Biomagnification, which is the increase in concentration of toxins up the food chain, especially affects you
27. Biomagnification of POPs occurs as they move up the food chain when predators consume prey, ingesting the POPs that have bioaccumulated in each prey item
28. Microplastics compound this problem by adding another more concentrated layer of exposure to the Biomagnification process
29. Biomagnification refers to the increased concentration of a toxic chemical the higher an animal is on the food chain
30. The process of a buildup of certain chemical substances or toxins at the higher trophic levels of a food chain is termed as Biomagnification
31. Bioaccumulation and Biomagnification 1
32. Biomagnification It is also known as bioamplification or biological magnification It is the increase in concentration of a pollutant that occurs in a food chain as a consequence of: 1.
33. Consequently, bioaccumulation, and in particular Biomagnification of MPs and associated chemical additives, are often inferred to occur in marine food webs
34. Biomagnification: Pollution affects populations of organisms within ecosystems
35. Figure 184.108.40.206: In Biomagnification the concentration of the persistent toxins (crosses) increase higher up the food chain
36. Biomagnification • Biomagnification, also known as bioamplification or biological magnification, is the increase in concentration of a substance, such as the pesticide DDT, that occurs in a food chain as a consequence of: • Persistence • Food chain energetics • Low rate of internal degradation/excretion of the substance (often due to water
37. ‘Vectors for POPs are the same as for heavy metals (i.e., ocean currents, precipitation, and Biomagnification through the food chain, especially the marine food chain).’ ‘Unfortunately, insecticides like DDT used to control the mosquitoes was found to ripple through the web of life in a process called Biomagnification, and proved to be
38. Biomagnification refers to the increase in concentration of pollutants as they move from one trophic level to the next
39. An apt example of Biomagnification will be when small fish eat contaminated microscopic organisms, and big fish eat the small fish.

42. This process is called Biomagnification, and it takes place when organisms higher in the food chain eat many of the smaller organisms that have bioaccumulated the chemical from the environment
43. Bioaccumulation and Biomagnification
44. Bioaccumulation & Biomagnification-Lab Background The concepts of bioaccumulation and Biomagnification (or biological magnification) are often confused
45. Biomagnification doesn’t occur with degradable chemicals/substances for example sugar, tea, cheese, milk etc

47. The slope of the simple linear regression between log10 transformed mercury (Hg) concentration and stable nitrogen isotope values (δ15N), hereafter called trophic magnification slope (TMS), from several trophic levels in a food web can represent the overall degree of Hg Biomagnification
Biomagnification is the process in which toxins are concentrated in an organism as larger animals continue to eat smaller animals.
Biomagnification, also known as bioamplification or biological magnification, is the increasing concentration of a substance, such as a toxic chemical, in the tissues of tolerant organisms at successively higher levels in a food chain.
Biological magnification occurs by increasing the toxicity of poisonous substances as those substances move up the food chain. An example of biological magnification and its dangers is any small fish that eats plankton that has been tainted with mercury.
Biological magnification definition, the increasing concentration of toxic substances within each successive link in the food chain. See more.
