The carbon cycle does not involve photosynthesis.

Concept: The above-given statement is true

A) Photosynthesis is the first process that takes place in the carbon cycle. By way of photosynthesis, carbon dioxide is incorporated into living tissue. The third process in the carbon cycle is called respiration. Following photosynthesis, the carbon dioxide will be expelled back into the atmosphere by plants and animals.

Importance of Carbon cycle
The carbon cycle is crucial to ecosystems because it transports carbon, a component necessary for life, from the atmosphere and seas into organisms and out again.

B) The first step is photosynthesis, which is the conversion of light energy into chemical energy in green plants and some other animals. It is the method by which plants produce food for their own needs.

The correct statement is the carbon cycle involves photosynthesis.

Hence, option B is the correct answer.
