Question

A plant and numerous snails occupy the same tightly closed aquarium. The aquarium is exposed to sunlight for 12 hours a day and has 2 inches of water in it. What would happen to the plant if you removed all the snails from the aquarium? The plant would die from lack of glucose. The plant would die from lack of oxygen. The plant will thrive because it can undergo both processes of photosynthesis and cellular respiration. The plant will thrive because it can photosynthesize but then it will die because it cannot perform cellular respiration.

Answer 1

The answer is D because plants intake CO2 through photosynthesis but cannot perform cellular respiration because that is the form of gaining energy in humans and other heterotrophic organisms. Hope this helps!

Answer 2

Answer: Option C

Explanation:

The plants has the ability to survive on its own. It can itself release carbon dioxide into the closed system and use the carbon dioxide for the process of photosynthesis.

The snails in the aquarium plays a major role in the releasing carbon dioxide and cleaning the aquarium.

The ability of the plant to perform photosynthesis needs carbon dioxide and water and releases oxygen in atmosphere. Without snails also the plants will be able to survive on their own.
