The process of photosynthesis is always shown first in the cycle.
The process of photosynthesis is always shown first in the cycle.

Only the compounds that contain carbon should be shown in the cycle.

The process of cellular respiration is always shown first in the cycle.

Answer 1

The correct statement is:

**Either of the processes of cellular respiration or photosynthesis can be shown first because a cycle has no start or finish.**

In a cyclical process like the carbon cycle, the sequence of the processes can vary, as the cycle continually repeats and does not have a definitive starting or ending point.
