A scientist is studying an acidic pool that contains large amounts of iron, SO4, CO2, and O2. Use the chart at the station to identify an organism capable of living in this environment and identify its class of ‘trophy’.

Acidophilic and acidotolerant eukaryotic microorganisms such as algae, amoebas, ciliates, heliozoan and rotifers, not to mention filamentous fungi and yeasts.

Explanation:

Acidophilic and acidotolerant eukaryotic microorganisms such as algae, amoebas, ciliates, heliozoan and rotifers are the organisms which can survive in highly acidic solution that have large amounts of iron, sulfur dioxide, carbondioxide, and oxygen molecule. In these organisms algae is autotrophic whereas archaea, bacteria, fungi, yeasts and protozoa are heterotrophic.

Answer and Explanation:

The ongoing reduction in the ocean's pH is called ocean acidification, which is caused by the uptake of CO2 (carbon dioxide) from the atmosphere. The burning of fossil fuels releases about one-quarter of carbon dioxide. When carbon dioxide dissolves in water, the water becomes more acidic, and the pH of waterfalls, such as pH 5 is ten times more acidic than pH 6. A small change in ocean water pH can have harmful effects on marine life, growth, reproduction and impacting chemical communication. In marine creatures, the structure of the skeleton is susceptible to acidity. All water contains oxygen and hydrogen. Most freshwater animals and plants cannot live in salty water, while clownfish need salty water to survive. Numerous algae, plants and algae plants can survive under acidic conditions; they make their energy from carbon dioxide and sunlight. Acidophiles can also survive in an acidic environment comprising sulfuric geysers and pools.
