Name 2 qualities of water which are significant for aquatic organisms.

Dear student,
Please find below the answer:

Two qualities of water which are significant for aquatic organisms are as follows:

1. Temperature: It is important for water animals as well as plants. This is because it affects the organism's ability to resist pollutants.
2. pH: It indicates the number of hydrogen ions present in the water and helps in identifying whether the water is acidic, basic and neutral.

Other qualities include turbidity of the water, amount of dissolved oxygen, dissolved solids etc.
