You are observing an organism.  It appears to extract energy stored in inorganic molecules like ammonia, nitrites and hydrogen sulfide; it uses carbon dioxide as its primary carbon source.  What kind of organism is it? (Hint: think nutrition groups)

A deer eats 25kg of herbaceous material per day. The herbaceous material is approximately 20% dry matter(DM) and has an energy content of 10MJ.(kgDM)^-1. Of the total energy ingested per day, 25%  is excreted as undigested material. Of the 75% that isn’t digested, 80% is lost to metabolic waste products and heat. The remaining 20% is converted to body tissue. How MJ are converted to body tissue on a daily basis? Calculate the percentage of energy consumed that Osborn’s converted to body tissue Draw a schematic of energy balance.
