Question

Explain eutrophication and biological magnification, with examples. ​

Answer 1

Answer:

Eutrophication is a natural process that occurs in lake or pond as that body of water. EXAMPLE – Algae. The increase in concentration of harmful chemical substances like pesticides in the body of living organism at each trophic level of food chain is called Biological magnification. EXAMPLE – Pesticides.

Answer 2

Answer:

Biological magnification refers to the process where toxic substances move up the food chain and become more concentrated at each level. ... An example of biological magnification and its dangers is any small fish that eats plankton that has been tainted with mercury. One example is an "algal bloom" or great increase of phytoplankton in a pond, lake, river or coastal zone as a response to increased levels of nutrients. Eutrophication is often induced by the discharge of nitrate or phosphate-containing detergents, fertilizers, or sewage into an aquatic system.
