Question

12. Where is the rate of primary production the lowest?

a. upwelling along coasts

b. in the middle of the current gyres

c. along the Equator

d. around Antarctica in the summer

e. coasts

Answer 1

Option B, in the middle of the current gyres

Step-by-step explanation:

The zones of upwelling have high productivity as they have adequate climate and weather condition along with availability of nutrients. The same is applicable for Equator and coastal regions. The productivity of Antarctica is low but not less than that of current gyres as in the middle of the current gyres there are high current streams that reduces the biological productivity.

Hence, option B is correct
