Answer 1

The correct response is:

The carbon source is carbon dioxide, and the plant receives it from the atmosphere.

In the Calvin cycle, carbon dioxide (CO₂) from the atmosphere is fixed and used to synthesize glucose. The other options provided are not accurate regarding the source of carbon for glucose production.
