Answer: Among the above mentioned organisms hawk will have the highest concentration of non biodegradable chemicals. The phenomenon is biomagnification.
Explanation: Biomagnification means the increase of contaminated substances or toxic chemicals that take place in the food chains.
When organisms in the higher food chain consume the organisms containing the toxins below their trophic levels, the toxins gradually become concentrated in the higher food chain. Because this is a repetitive process in the ecosystem and throughout the entire food chain, the higher organisms are the ones that will accumulate most of the toxins.
