How is respiration related to photosynthesis?

1. Photosynthesis uses oxygen and produces carbon dioxide, while respiration uses carbon dioxide and produces oxygen.

2. Photosynthesis uses sunlight to create energy, while respiration transfers energy created by cellular processes.

3. Photosynthesis captures carbon dioxide from the environment and converts it into sugar, while respiration converts sugar into energy.

4. Photosynthesis produces glucose and respiration consumes glucose.

The correct answer is: Photosynthesis captures carbon dioxide from the environment and converts it into sugar, while respiration converts sugar into energy.

Context Respiration and photosynthesis are two important processes that occur in plants. They are closely related and complement each other, allowing plants to survive and thrive in their environment. While both processes involve the exchange of gases and the production of energy, it is important to understand how they are related to each other. Option A is incorrect because it confuses the roles of oxygen and carbon dioxide in respiration and photosynthesis. In photosynthesis, plants use carbon dioxide and produce oxygen, while in respiration, plants use oxygen and produce carbon dioxide. Option B is incorrect because it only describes how energy is created in photosynthesis and respiration separately, without explaining how they are related to each other. Option D is incorrect because it only mentions the production and consumption of glucose, without explaining how this relates to photosynthesis and respiration. The correct answer is option C because it accurately explains the
