How have they evolved to deal with this extreme environment? Archaeans are single-celled prokaryotes. Regardless of varying environmental conditions, the ability of thermophiles to thrive in extremely hot environments lies in extremozymes, enzymes geared to work in extremely high temperatures. R. Berlemont, C. Gerday, in Comprehensive Biotechnology (Second Edition), 2011. In ecology, microorganisms are classified by the type of habitat they require, or trophic level, energy source and carbon source. Though there are significantly less atmospheric microorganisms than there are in oceans and in soil, there is still a large enough number that they can affect the atmosphere (Amato, 2012). from Microbes; 750L - 890L. with more specific applications in the future. catalase, rubisco, carbonic anhydrase). Lexile Levels 560L - 740L 750L - 890L 900L - 1040L . The amino acids of these extremozymes have special tricks to retain their twisted and folded 3D structures in high heat, where other enzymes would unfold and no longer work.
