Which of the following pairs are correctly matched?
(A) Poikilosmotic – Animals show osmotic changes with respect to the environment.
(B) Homoiosmotic – Animals maintain body fluid concentrations constant irrespective of fluctuations in the
environmental concentrations.
(C) Euryhaline – Animals withstand aquatic media of wide range of salt concentrations.
(D) Stenohaline – Animals survive with a wide range of salinities

The correct option is D A, B, C
Poikilosmotic are animals which show osmotic changes with respect to their environment. If the osmotic pressure changes outside, the osmotic pressure of body also changes.
Homoiosmotic are animals which maintain a constant osmotic pressure insde heir body irrespective of the osmotic pressure of the environment.
Euryhaline are organisms which can survive wide range of salt concentrations. They can survive in salty as well as fresh water.
Stenohaline are organisms which can survive a narrow range of salt concentration. They can survive only in salt water or fresh water but not in both.
