34. Which of these BEST explains how the emission of pollutants such as carbon dioxide, sulfur dioxide, and nitrogen oxide from a factory into the air may harm organisms that live on land or in water? • The pollutants may react with water vapor to form acid precipitation, which harms land plants and aquatic organisms. • The release of carbon dioxide into the sir causes an increase in carbon dioxide levels, making photosynthesis difficult. • Nitrogen oxide released into the air joins with water vapor to form nitrogen-rich rain (fertilizer) that stimulates plant and algal growth. • Sulfur dioxide increases the growth of water plants, crowding out fish.
