A simple food chain is: algae → small fish → large fish → eagle. The pesticide level in the algae is 0.01 ppm. Which row shows a likely pattern of pesticide concentration (in ppm) along this food chain due to biomagnification?
- algae 0.01, small fish 0.005, large fish 0.002, eagle 0.0005
- algae 0.01, small fish 0.08, large fish 0.6, eagle 4.5
- algae 0.01, small fish 0.01, large fish 0.01, eagle 0.01
- algae 0.01, small fish 0.02, large fish 0.01, eagle 0.02
