What is the difference between an organism being piezophilic and piezotolerant?
What will be an ideal response?
Answer: An organism that is philic grows best under a certain condition, so piezophilic organisms grow best at a pressure greater than 1 atmosphere. Tolerant organisms are capable of withstanding a particular condition but do not necessarily grow best under that condition. Piezotolerant organisms can tolerate pressures beyond 1 atmosphere, but they grow best at 1 atmosphere.
