Aerosols, decrease primary productivity by

1. Decreasing \( O_{2} \) concentration
2. Preventing \( N_{2} \) fixation
3. Reducing photosynthesis
4. None of the above

Correct answer: Reducing photosynthesis

Solution

Aerosols can scatter and absorb incoming solar radiation, reducing the light available for photosynthesis. With less photosynthesis, plants and phytoplankton make less organic matter, so primary productivity decreases.
