Chemosynthetic bacteria are unique:

Question

Quizplus · Accepted Answer

Chemosynthetic bacteria are unique because they use energy derived from chemicals (such as hydrogen sulfide, methane, or ammonia) to produce their own food, rather than relying on sunlight like most other organisms do. This process is called chemosynthesis, and it allows these bacteria to survive in extreme environments, such as the deep sea where no sunlight can reach.

Answer: D
 Chemosynthetic bacteria are very common in the twilight depths of the ocean, where sunlight is rare and alternative sources of energy are needed for life to survive. These bacteria form the basis of entire ecosystems in areas such as hydrothermal vents and cold seeps, where they provide food for other organisms such as tube worms, clams, and shrimp.
