Question

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.

Answer 1

Answer: Y can be sea

Explanation:

For aquatic organisms, the quality (chemical composition, PH) of water is very important. The salt concentration (measured as salinity in parts per thousand), is less than 5 parts per thousand in inland waters, 30-35 parts per thousand in the sea and more than 100 parts per thousand in some hyper saline lagoons. Many fresh water animals cannot live for long in sea water and vice versa because of the osmotic problems they would face.

So, the correct answer is 'Y can be sea'.
