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.
