Question

20 explain the phenomenon of biological magnification

Answer 1

Answer:

Biological magnification is termed as the phenomenon of the accumulation of any toxins to concentrate at a very dangerous level in the tissue level of the organism, which may damage the mechanism of the organism.

Explanation:

Biological magnification, also called bioamplification is associated with the food chain. The toxins which accumulate in the lower levels of the food chain, for example, the plants, pass successively the next consumer, to the herbivore , like chickens and then, to the higher consumer, the carnivore, example the man. The amount of toxins get accumulated and increased in each successive  level of the chain. Ultimately a large concentration of the toxin is accumulated to top organism of the food chain and thus it has a great impact of damage to the organism.

The following is the flow chart of the biological magnification of DDT[a pesticide](note the examples to get a better explanation):

Water                           Plankton                     Fish

(0.02 ppm)                  (5.0 ppm)                 (240 ppm)
