Answer 1

Answer 51. Barophiles are the organisms that occur at high pressure.

Answer 52. Halophiles are the organisms that occur at high salt concentration.

Answer 53. Acidophile, they grow at pH less than 3.

Answer 54. Alkaliphile, they grow at pH greater than 9.

Answer 55. Litho autotrophs,inhabit the rocks and are autotrophs.

Answer 56. Obligate anaerobic organisms do not grow in presence of oxygen.

Answer 57. Microaerophiles require very less oxygen for their respiratory metabolism.

Answer 58. Xerophiles grow in the absence of water.

Answer 59. Toxitolerant.

These can tolerate toxic environments.
