Answer 2

It's like photosynthesis, in that it's used to provide nutrients to keep a cellular organism alive without using oxygen as an input... except it relies on chemical reactions only, and not sunlight.  It works by creating biomolecules through oxidation reactions, using methane, hydrogen sulfate, etc as inputs.  Here's an example of a chemosynthesis reaction, using hydrogen sulfide and CO2 as the input.

CO2 + O2 + 4{H2S} → CH2O + 4{S} + 3{H2O}

It's most common in unicellular organisms that live underwater in dark areas where sunlight is not available.  In other environments, these organisms are outcompeted by phototrophs and eutropic organisms.
