What is the biological magnification?

Biological magnification, also known as biomagnification or biomplification, explains why the substance occurs at higher concentrations of organisms in a given food chain than in lower organisms in the food chain. This happens because the creatures high in the food chain, such as predators, feed on creatures that are lower in the food chain, and absorb substances from organisms that consume, except substances that directly absorb the environment. In some cases, the biological enlargement process may be harmful to organisms that are high in the food chain because they absorb harmful substances from all organisms they consume. While a small amount absorbed from the environment could be completely harmless, the amount consumed from food sources could be added and harmful.

Several things must apply about the substance to make a biological magnification. The substance must be able to absorb at a certain point in the food chain, otherwise IT could not be zvštěn. It must not easily decompose through the environment because it would remove it from the food chain. It must be difficult for organisms to break down or spend safely, as digestion would also prevent the organisms to prevent the organisms higher in the food chain.

While biological enlargement can technically become any substance that meets these criteria, is usually studied to enlarge harmful substances such as fertilizers, pesticides and heavy metals. These substances often accumulate in the body of the body, because they cannot break in water and get out of the body with urine. When the body higher in the food chain consumes creatures lower in the food chain, it absorbs fats in the intestine. With these fats come substances that previously accepted another organism and all harmful effects to these substances with them. Many plants, water and earthly, are susceptible to the absorption of different substances because often posedThey can use their effective digestion.

One of the primary substances that scientists study in relation to biological enlargement is the pesticide dichlorodifenyltrichloethan, better known as DDT. DDT has a long and controversial history; It is a very effective pesticide, but some studies have shown that it may have a harmful environmental effect and health and animal health. It is also difficult for many organisms to break it effectively, so it is often enlarged by food pyramids.
