The organism that doesn't require sunlight to live is chemosynthetic bacteria. Here's why:

* Chemosynthetic bacteria obtain energy from the oxidation of inorganic compounds (like hydrogen sulfide, methane, or ammonia) rather than sunlight. This process is called chemosynthesis.

* Trees and algae are photosynthetic organisms that rely on sunlight for energy.

* Photosynthetic bacteria also require sunlight for energy production.
