Most living organisms cannot survive at temperature above `45^(@)C^(@)`. How are some microbes able to live in habitats with temperatures exceeding ` 100^(@)C?`

Explanation

Most living organisms cannot survive at temperatureabove `45^@C` because very high temperature causes denaturation of their enzymes . But certain bacteria , cyanobacteria , shelled protozoans, etc. are known to survive even in thermal springs. Tolerance power to the extrems of temperature varies from species to species e.g. Certain bacteria and cyanobacteria have thermal - resistant enzymes and peculiar cell wall.
