Multiple Choice

In the context of the carbon cycle, how does the process of photosynthesis contribute to the movement of carbon?

Photosynthesis breaks down organic compounds into carbon dioxide, which is then absorbed by plants.

Photosynthesis releases carbon dioxide into the atmosphere, increasing carbon levels.

Photosynthesis converts carbon dioxide into organic compounds, which are used by plants and other organisms.

Photosynthesis stores carbon in the form of fossil fuels, which are later used by humans.

Verified step by step guidance

Understand the role of photosynthesis in the carbon cycle: Photosynthesis is a process used by plants, algae, and some bacteria to convert light energy, usually from the sun, into chemical energy stored in glucose, a type of sugar.

Identify the reactants and products of photosynthesis: The general equation for photosynthesis can be represented as: 6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂. This shows that carbon dioxide (CO₂) and water (H₂O) are converted into glucose (C₆H₁₂O₆) and oxygen (O₂).

Explain the conversion of carbon dioxide: During photosynthesis, carbon dioxide from the atmosphere is absorbed by plants and used to form glucose, an organic compound. This process effectively removes carbon dioxide from the atmosphere and incorporates it into plant biomass.

Discuss the significance of organic compounds: The glucose produced is used by plants for energy and growth, and it can also be converted into other organic compounds such as cellulose and starch, which are essential for plant structure and energy storage.

Clarify the impact on the carbon cycle: By converting carbon dioxide into organic compounds, photosynthesis plays a crucial role in reducing atmospheric CO₂ levels and providing energy-rich compounds that are used by plants and other organisms, thus contributing to the movement and storage of carbon within the ecosystem.
