Name and describe one natural factor that can cause the pH of water to decrease. How does a reduced pH affect plant and animal life?
this is what I have written down so far:
Eutrophication is a natural phenomenon that causes the pH level of water to decrease. As the algal blooms take place, levels of oxygen are decreased resulting in dead-zones and the death of many animals. A reduced pH level causes the plants and animals that cannot survive in the resulting pH to die. Correspondingly, the decayed matter of the animals increases levels of carbon dioxide, which results in an even lower (decreased) pH level, due to the fact that an increase in carbon dioxide reduced the pH level (in water). Essentially, a very dangerous positive feedback loop occurs because the animals and plants keep on dying, and their decayed matter increases levels of carbon dioxide which lowers the pH even further.
I could not find anything substantial or anything that made sense to me. I thought a lot and since increased levels of carbon dioxide causes pH levels to decrease, I thought I would write about eutrophication, with the justification provided in the answer I wrote in the "what did you do so far?" section.
Is this a good answer? How can I improve my answer? And if this is not substantial, then what should I write about?
