Question

Which of the following is NOT a direct effect of El-Nino?

• A. Distortion of equatorial atmospheric circulation
• B. Irregular seawater evaporation
• C. Rise in plankton population
• D. Reduction in fish population

Answer 1

Answer:

C. Rise in plankton population

• El-Nino leads to a reduction in plankton due to the warmer surface waters which limit nutrient upwelling.

• This, in turn, negatively impacts fish populations that depend on plankton.
