Question

The following organisms form a food chain. Insect, Hawk, Grass, Snake, Frog Which of these will have highest concentration of non-biodegradable chemicals? Name the phenomenon.

Answer 1

*From the following organisms hawk will have highest concentration of non biodegradable chemicals

*This is because the concentrations of non biodegradable chemicals increases from 1st trophic level to the tertiary trophic level

*And this phenomenon is known as bio-magnification

Answer 2

The phenomenon is called Biomagnification. Hawk is the organism with highest concentration of non-biodegradable chemical.

Explanation:

• Biomagnification is also known as Bio-amplification, meaning the bio-chemical substances increase exponentially as they move along the food chain.
• It is a  phenomenon where the non- biodegradable substances get accumulated  in the body of the organism instead of being eliminated.
• This pattern is followed up the food chain. Hence the maximum concentration of non biodegradable substances is found in organism in the highest rank of the food chain.
• This food chain is as "Grass, Insect, Frog, Snake and Hawk, hence maximum concentration is found in Hawk.
