Question

If the number of photosynthetic organisms on the earth decreased drastically, which would happen as a result? Less water would be available on the earth’s surface. Less solar energy would reach the earth’s atmosphere. More oxygen gas would be found in the atmosphere. More carbon dioxide gas would be found in the atmosphere.

Answer 1

Lithe correct answer is a

Answer 2

More carbon dioxide gas would be found in the atmosphere.

Step-by-step explanation:

Photosynthetic organisms convert carbon dioxide in air to oxygen through photosynthesis, while other non-photosynthetic organisms only consume oxygen and release carbon dioxide through respiration, they do not undergo photosynthesis.

When the number of photosynthetic organisms on the earth decreased drastically, the carbon dioxide released from other non-photosynthetic organisms cannot be converted to oxygen, so carbon dioxide in air accumulates.
