Three water bodies were tested for salinity of water. Water body X showed salt concentration as 3 parts per thousand, Y showed 35 parts per thousand and Z showed 110 parts per thousand salinity.
Select the correct option regarding this.
X can be a lagoon
Y can be a sea
Z can be an inland river
None of these
As we have already studied in Major Abiotic Factors: Temperature & Water -
Tolerance of variation of water on species -
Some organisms are tolerant of a wide range of salinities (euryhaline) but others are restricted to a narrow range (stenohaline).
- wherein
Many freshwater animals cannot live for long in sea water and vice versa because of the osmotic problems, they would face.
Hence, the correct option is (b).
