Depend directly on solar energy, and trap it to convert carbon dioxide into complex sugar molecules via photosynthesis. b. Chemotrophs i. Obtain energy from chemical compounds obtained directly or indirectly from photographs through either respiration or fermentation 1. Respiration a. A metabolic reaction that generates energy in the presence of oxygen (“aerobic” process) i. This reaction occurs after we consume fruits, breads, etc. 2. Fermentation a. A metabolic reaction that generates energy in the absence of oxygen i. This reaction is carried out by LACTIC ACID
