To determine whether the unknown bacterium is a chemotroph, the appropriate method would be:
**growing the bacterium in a sulfur solution to see if it breaks the inorganic molecules down**
Chemotrophs obtain energy by oxidizing inorganic or organic substances. Testing the bacterium's ability to break down inorganic molecules is a direct way to assess its metabolic capabilities and determine whether it is a chemotroph.
