Multiple Choice

What is the role of photosynthesis in the carbon cycle?

Photosynthesis converts carbon dioxide into organic compounds, reducing atmospheric CO2 levels.

Photosynthesis is responsible for the decomposition of organic matter.

Photosynthesis releases carbon dioxide into the atmosphere, increasing CO2 levels.

Verified step by step guidance

Understand the process of photosynthesis: Photosynthesis is a biochemical process in which plants, algae, and some bacteria 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).

Analyze the role of photosynthesis in the carbon cycle: Photosynthesis plays a crucial role in the carbon cycle by removing carbon dioxide from the atmosphere and incorporating it into organic compounds, which are used by plants and other organisms for energy and growth.

Evaluate the impact of photosynthesis on atmospheric CO2 levels: By converting CO2 into organic matter, photosynthesis helps reduce the levels of carbon dioxide in the atmosphere, which is essential for maintaining the balance of the carbon cycle.

Clarify misconceptions: Photosynthesis does not decompose organic matter or release carbon dioxide into the atmosphere. Instead, it is a process that synthesizes organic compounds from carbon dioxide and water, contributing to the reduction of atmospheric CO2 levels.
