A student uses ball and stick models of substances to show how carbon dioxide is recycled by plants. Which statement is true about the model of the cycles? A. The process of cellular respiration is always shown first in the cycle B. The process of photosynthesis is always shown first in the cycle c. Either of the processes of cellular respiration or photosynthesis can be shown first because a cycle has no start or finish D. Only the compounds that contain carbon should be shown first in the cycle

Answer 1

The correct statement about the model of the cycles is:

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

In a cycle, the processes can be represented in any order, as they continuously interact with each other in nature.
