Question

Scientists have discovered a rare, ancient bacteria thriving on the ocean floor. This bacteria uses sulfur released by thermal vents, as well as dissolved oxygen and carbon dioxide in the water, to create sugar and break it down for energy. This process is called __________ .

Answer 1

chemosynthesis is the process.

Answer 2

Answer:

Chemosynthesis

Explanation:

All organisms make food either through photosynthesis or Chemosynthesis

.In this case bacteria are creating sugar (food) through all the course of activities mentioned here.  Bacteria that live deep under the ocean uses energy released by any chemical reaction to make food (sugar) for themselves.

The chemical reaction involved here is as follows -  

CO2 + 4H2S + O2 -> CH20 + 4S + 3H2O
