Answer:
Option-A
Explanation:
In the given question, the artificial ecosystem was prepared by the scientist which included the animals and plants. The light and dark conditions were controlled by a switch and bulb.
In the beginning, the amount of Carbon in the form of carbon dioxide was low due to the utilization of carbon dioxide by plants to perform photosynthesis. Then the amount of carbon dioxide increased in the atmosphere, the reason could be due to less consumption of carbon dioxide. The carbon dioxide is not uptake by plants during night conditions when photosynthesis process slowed down or stops.
Therefore, the dark condition was created by the scientist by switching off the lights and the number of energy molecule decreased as no photosynthesis was occurring.
Thus, Option-A is the correct answer.
