1 Breeding of crops that are rich in minerals and vitamins, good proteins and healthier fats for human health
2 Increase in concentration of the toxicant at successive trophic levels
3 Exploring at molecular, Genetic and species level diversity for the products of economic importance
4 Decomposition of organic waste in water by the action of microbes
Explanation:
Bio-magnification refers to the increase in the concentration the toxicant at successive trophic levels of non-degradable pollutants substances at successive trophic level in a food chain. This happens when a toxic substance consumed by the organisms of a trophic level cannot be metabolized.
