Organisms that utilize inorganic molecules (such as hydrogen sulfide), carbon dioxide and water to form organic molecules in the absence of sunlight are called a. heterotrophs b. chemoautotrophs c. autotrophs d. photoautotrophs

b. chemoautotrophs

Explanation: chemoautotrophs are organisms that obtain energy, molecules, water by the oxidation of electron donors in their environments. Chemoautotrophs are able to synthesize their own organic molecules from inorganic sources. They are different from phototrophs who requires sunlight to make their own food

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.

carbon atoms, hydrogen, oxygen, and nitrogen.
