Question

A student uses ball-and-stick models of substances to show how carbon is recycled by plants. Which statement is true about the model of the cycles?(1 point)
Responses

Only the compounds that contain carbon should be shown in the cycle.
Only the compounds that contain carbon should be shown in the cycle. - no response given

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

The process of cellular respiration is always shown first in the cycle.
The process of cellular respiration is always shown first in the cycle. - no response given

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

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 cycle, such as the carbon cycle, there is no specific starting or ending point, and both photosynthesis and cellular respiration are interconnected processes that contribute to the recycling of carbon.
