Question

the numbers in the food chains shown here represent the amount of oil droplets consumed. which food chain best shows the results of biomagnification after an oil spill? stingray 1,000 → seahorse 2,500 → copepods 10 seahorse 10 → copepods 2,500 → stingray 1,000 copepods 1,000 → stingray 10 → seahorse 2,500 copepods 10 → seahorse 1,000 → stingray 2,500

Explanation:

Biomagnification is the process by which the concentration of a pollutant (here oil droplets) increases as you move up the food - chain. Lower - level organisms consume small amounts of the pollutant, and higher - level organisms that eat many of the lower - level organisms accumulate more of the pollutant. So, the amount of oil droplets consumed should increase from the bottom of the food - chain to the top.

Answer:

D. Copepods 10 $\longrightarrow$ Seahorse 1,000 $\longrightarrow$ Stingray 2,500
