Answer

Brief Explanations:

  • Option a: Ozone is a component of air pollution. High - level ozone exposure can damage plant tissues, reduce photosynthesis, and affect plant growth.
  • Option b: Mercury is a pollutant that can enter the ecosystem through air pollution (e.g., from coal - fired power plants). It can bioaccumulate in organisms like bats. Endangered bat species being affected by high mercury levels is a consequence of air pollution.
  • Option c: Nitrogen deposition (from air pollutants like nitrogen oxides) can change alpine ecosystems. It can alter soil chemistry, favor some plant species over others, and disrupt the balance of the ecosystem.

Since all of the options (a, b, and c) are valid ways that air pollution in US National Parks is affecting the environment.

Answer:

D. all of the above
