Answer:
All of the above are true.
Explanation:
The prokaryotic organisms are the unicellular primitive organism which was formed in the primitive time when the conditions on the Earth were harsh.
The prokaryotes developed the metabolism to survive in the extreme conditions and were recognised as the archaebacteria. These bacteria can tolerate extreme condition like hot temperature called thermophilic conditions. These thermophiles can grow at higher temperature conditions than the eukaryotes.
The thermophiles are non-phototrophic organism as they do not utilize the light energy to produce energy as phototrophic organisms does.
Thus, all of the true is correct.
