Question: 149: Breeding crops with higher levels of vitamins and minerals or higher proteins and healthier fats is called :
(1) Bio-fortification
(2) Bio-accumulation
(3) Bio-magnification
(4) Bio-remediation
Answer: Option (1)
Explanation:
Bio-fortification is the process of breeding crops to increase their nutritional value.
This includes enhancing the levels of vitamins, minerals, proteins, and healthy fats in food crops.
The main aim of bio-fortification is to improve the nutritional quality of food and reduce nutrient deficiencies in human populations.
Bio-accumulation refers to the accumulation of substances like pesticides in the body of an organism.
Bio-magnification is the increase in concentration of toxic substances along the food chain.
Bio-remediation involves the use of organisms to remove pollutants from the environment.
Therefore, breeding crops with higher nutritional content is called bio-fortification.
