Air Test Biology

A student was studying how a change in abiotic factors can influence living organisms. She set up the experiment as follow:

1) Fill two glass fish tanks, labeled Tank A and Tank B, with 5 liters of water each.
2) Add a small fish and several plants to each tank.
3) Seal both tanks so that no air can leave or enter.
4) Place Tank A in a bright room and Tank B in a dark room.

The student noticed after 45 hours, the fish in Tank B died while the fish in Tank A remained healthy. Based on the results of the experiment described above, what is the best explanation for why the fish in Tank A lived and the fish in Tank B died?

• Fish died in Tank B due to a lack of carbon dioxide.

• Fish died in Tank B because the tank was sealed.

• Fish died in Tank B due to lack of oxygen.

• Fish died in Tank B because the temperature was too low.
