Question: What is biological magnification class 10?
Biological magnification, also known as bioamplification, is the accumulation and concentration of a certain chemical or substance throughout the food chain. This is a process that can occur naturally or can be accelerated by human activities like pollution. In biological magnification, toxins from a particular source accumulate in higher concentrations as they move up the food chain. For example, as a result of increased levels of DDT in water sources, fish that live in the contaminated area contain higher levels of the pesticide. When another animal, such as a bird, eats the fish, it accumulates even higher levels of DDT. The DDT continues to accumulate as it moves up the food chain, resulting in immense concentrations at the top of the pyramid.
This process can be harmful to organisms because the toxins can build up to lethal levels in the tissues and organs of the organisms that feed on the contaminated organisms. In some cases, the pollutants accumulate in such concentrations that they can be passed on to humans who consume the contaminated animals. Biological magnification can have devastating effects on animal and human populations, leading to decreased fertility, impaired nervous and immune systems, and even death.
