Explain how extremes of pH limit growth. Majority of organisms live or grow in habitats between pH 6 and 8 obligate acidophiles: Euglena mutabilis-alga that grows between 0 and 1.0 pH Thermoplasma-archae that lives in hot coal piles at a pH of 1 to 2, and would lyse if exposed to pH 7.

Common causes of wildfires include lightning, human carelessness, arson, volcano eruption, and pyroclastic cloud from active volcano.
