What can be a result of increased levels of acid precipitation in aquatic environments?

Increased levels of acid precipitation in aquatic environments can lead to a reduction in biodiversity. Acid precipitation, often caused by the release of sulfur dioxide and nitrogen oxides into the atmosphere, results in the acidification of water bodies. This change in pH can have detrimental effects on many aquatic organisms, particularly those that are sensitive to changes in acidity, such as fish and certain invertebrates. As these organisms struggle to survive in more acidic conditions, their populations may decline, which can disrupt the balance of the ecosystem.

Furthermore, a reduction in the diversity of species can lower the resilience of the ecosystem to further environmental changes and lead to a cascade of negative effects within the food web. For example, if keystone species are affected, the entire structure of the aquatic community may be compromised, leading to fewer species and variation on an ecological level.

In contrast, the other options present outcomes that are generally not associated with increased acid precipitation. For instance, fish populations typically do not improve under these conditions, and increased acidity usually leads to decreased water clarity rather than an increase. Algae growth can sometimes be affected by nutrient dynamics; however, the relation with acid precipitation does not lead to a general boost in growth. Thus, the most accurate result of acid
