the lake, which organisms would contain the
highest concentration of the chemical fertilizer?


A. diatoms and algae
B. zooplankton
C. fishes and crabs
D. large-sized fishes

Answer 1

Thank you, I was thinking the that it might be D or B. But then for D I was thinking about the 10% rule about the energy is less as it goes up, and with B it might have the most because it got it directly from the producer?

Answer 2

Okay thank you!
