What are examples of freshwater and marine water pollution? What is the basic information about water pollution? Explain the causes and consequences of eutrophication. What does a graph showing pH levels in species survival indicate?
Understand the Problem
The provided text offers a detailed overview of water pollution, including examples, basic information, causes and consequences of eutrophication, and impacts on species survival related to pH levels. It is likely that the user is looking for a comprehensive understanding of various aspects of water pollution.
Answer
Freshwater pollution involves chemicals; marine pollution includes oil spills. Eutrophication is caused by excess nutrients leading to oxygen depletion. pH graphs show survival impact at extreme levels.
Freshwater pollution often includes runoff carrying agricultural chemicals into rivers and lakes, while marine pollution may involve oil spills and plastic debris. Eutrophication is caused by nutrient pollution (nitrogen and phosphorus), leading to algal blooms that deplete oxygen. pH graphs indicate species' survival may be compromised at extreme pH levels.
Answer for screen readers
Freshwater pollution often includes runoff carrying agricultural chemicals into rivers and lakes, while marine pollution may involve oil spills and plastic debris. Eutrophication is caused by nutrient pollution (nitrogen and phosphorus), leading to algal blooms that deplete oxygen. pH graphs indicate species' survival may be compromised at extreme pH levels.
More Information
Eutrophication can result in 'dead zones' where aquatic life cannot survive due to low oxygen. This often impacts coastal and freshwater bodies globally. pH levels influence species survival; certain species are more tolerant of pH extremes than others.
Tips
Confusing the causes of marine vs. freshwater pollution is common. Ensure the distinction between the types (e.g., chemicals vs. plastics) and the processes they trigger (e.g., algal blooms vs. hypoxia).
