Question

In the carbon cycle, carbon dioxide and water are converted to glucose and oxygen by ________. Group of answer choices

Answer 1

Photosynthesis is the process in the carbon cycle where carbon dioxide and water are converted to glucose and oxygen by plants using sunlight.

Step-by-step explanation:

In the carbon cycle, carbon dioxide and water are converted to glucose and oxygen by the process of photosynthesis. Plants use the energy of sunlight to transform carbon dioxide (CO₂) and water (H₂O) into glucose (C₆H₁₂O₆) and oxygen gas (O₂). This reaction is crucial for the replenishment of oxygen in our atmosphere and is represented by the chemical equation: 6CO₂ + 6H₂O + sunlight → C₆H₁₂O₆ + 6O₂. In this process, carbon dioxide is reduced to glucose, while water is oxidized to oxygen gas, forming the building blocks for more complex carbohydrates, as well as plant proteins and oils.

Answer 2

Photosynthesis

Step-by-step explanation:

In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process.
