Question

Look at an ocean system below.
Phytoplankton
produce half of
the world's oxygen
Shrimp feed on
plankton and also
need oxygen to live
Salmon feed on
shrimp and need
oxygen to live
People often eat
salmon. We also
need to breathe
oxygen to live
What would most likely happen if the number of shrimp decreased?
O A. The plankton population would not change.
OB. The salmon population would increase.
O C. The salmon population would not change.
O D. The plankton population would increase.

Answer 1

Answer: D

Explanation:

If the shrimp population, which consumes plankton, decreases that would mean the plankton would have to increase. The salmon eat shrimp so less food means less salmon. The salmon population would have to change because their source of food is becoming more scarce. So in the end it would be D because the planktons main predators are decreasing.
