Thermoacidophiles are archaea that live in extremely environments with a pH, such as geysers, thermal vents, and near volcanoes. These archaea are , meaning that they reduce into organic compounds. These archaea use to reduce , releasing protons and as by-products. Compounds containing are typically used as terminal electron acceptors. Because concentrations of protons contribute to a pH, it would make sense that these organisms are found in environments.

Photosynthesis uses co2 and cellular respiration produces co2. we call the point when the two processes are in balance--when there is no net production of co2--the compensation point. how might you limit one of the processes in order to achieve a compensation point?
