What process involves the basic unit harnessing energy from sunlight?

  1. Photosynthesis

  2. Chemosynthesis

  3. Condensation

  4. Sublimation

The correct answer is: Photosynthesis

Photosynthesis is the process by which plants, algae, and some bacteria convert sunlight into chemical energy to fuel their cellular processes. It is the basic unit of harnessing energy from sunlight. Chemosynthesis, on the other hand, is a similar process but uses inorganic compounds instead of sunlight to produce energy. Condensation is a physical process in which water vapor turns into liquid. Sublimation is a process in which a solid turns directly into a gas without going through the liquid phase, and does not involve harnessing energy from sunlight. Therefore, A is the only correct answer.
