Question

Why is photosynthesis important to the carbon cycle?

A) It releases carbon dioxide into the atmosphere.
B) It consumes carbon dioxide during the dark reactions.
C) It converts carbon dioxide into glucose.
D) It increases carbon dioxide levels in the soil.

Answer 1

Photosynthesis is vital to the carbon cycle because it converts carbon dioxide into glucose, reducing atmospheric carbon dioxide levels and contributing to the balance of gases.

Step-by-step explanation:

Photosynthesis is crucial to the carbon cycle because it helps to regulate the levels of carbon dioxide in Earth's atmosphere. During photosynthesis, carbon dioxide is consumed by plants and is used, along with water and sunlight, to produce glucose and oxygen.

This process transforms carbon dioxide, a key greenhouse gas, into organic molecules, helping to maintain a balance of gases in the atmosphere and providing the foundation for the food web.

The correct answer to the student's question, 'Why is photosynthesis important to the carbon cycle?' is C) It converts carbon dioxide into glucose. This aligns with how photosynthesis pulls carbon dioxide out of the atmosphere and incorporates it into carbohydrates, which are vital for the growth and energy needs of plants and other organisms that feed on them.
