Question

Fertilizer runoff causes an increase in the dissolved nutrients of the ecosystem shown in the food web below. This causes the number of phytoplankton to double.

How will this most likely affect the other species in this ecosystem?
A.
The shrimp population will increase which will cause an increase in the squid population.
B.
The shrimp population will decrease which will cause an increase in the squid population.
C.
The shrimp population will decrease which will cause an increase in the sperm whale population.
D.
The shrimp population will increase which will cause a decrease in the sperm whale population.

Answer 1

I believe the answer is A because if shrimp eat phytoplankton, and squid eat shrimp this should work. I am not positive but I hope this helps.
