In a local park in an urban area, there are many factories. A concerned citizen noticed that there are a lot of dead fish in the pond at the park. The citizen asked city leaders for help. After studies were conducted around the pond site, scientists determined that it was probably nitric oxide causing the problem. What effect does the release of nitric oxide have on the ecosystem?
O It reduces the amount of light plants have available to them, which lowers rates of photosynthesis.
O It produces acid rain, which can cause the water of lakes and streams to become much more acidic.
O It provides an additional source for the nitrogen cycle to use as it strives to maintain equilibrium with the environment.
O It prevents bacteria from performing decomposition at levels that are needed to maintain balance in the ecosystem
