Biology CLEP Prep Practice Exam

Which of the following captures energy from the sun?

1. Photosynthesis

2. Respiration

3. Sublimation

4. Condensation

The correct answer is: Photosynthesis

Photosynthesis is the process by which plants use sunlight to convert water and carbon dioxide into energy in the form of glucose. It is a vital process in maintaining life on Earth and is the only choice that directly captures energy from the sun. Respiration, sublimation, and condensation do not capture energy from the sun. Respiration is the process of converting glucose into ATP for cellular energy, sublimation is the process of a solid turning directly into a gas, and condensation is the process of water vapor turning into liquid. While sunlight may be involved in these processes, they do not directly capture energy from the sun. Therefore, they are incorrect choices.
