A student measured the amount of oxygen and carbon dioxide


Asked by wiki @ in Biology viewed by 41 People


A student measured the amount of oxygen and carbon dioxide dissolved in an aquarium containing aquatic plants and snails. Why did the snail die after the aquarium was kept in the dark for 10 hours?

Answered by wiki @



The nail breathes oxygen to live. The nail breathes the oxygen dissolved in the water.


Given that the aquarium is a small bioma there is not enoguh source of oxygen to replace the oxygen consumed by the snail, except for the oxygen produced by the aquatinc plants inside the aquarium.


Plants produce oxygen through the process named photosynthesis. Photosynthesis requires light.


Given that the aquarium is kept dark, the aquatic plants cannot carry out the process of photosyntthesis and so there will not be generation new oxygen and the snails will die after they do not have oxygen to breath.
