1. Water is liquid, so it carries materials around in the body.
2. Water is polar, so it dissolves many kinds of molecules, has surface tension, cohesion, etc.
3. Water resists temperature change, so it gives a more constant environment for aquatic organisms.
4. Water expands when it freezes, so it breaks rocks into soil, it forms on the tops of bodies of water leaving a habitat underneath, ...

Water contains dissolved oxygen .This helps the aquatic organisms to sustain in water .
Water is also central to photosynthesis and respiration. Photosynthetic cells use the sun's energy to split off water's hydrogen from oxygen. Hydrogen is combined with CO2 (absorbed from air or water) to form glucose and release oxygen.
Water is also central to acid-base neutrality and enzyme function.
From a biological standpoint, water has many distinct properties that are critical for the proliferation of life that set it apart from other substances. It carries out this role by allowing organic compounds to react in ways that ultimately allow replication.

Does not change temperature easily, is a liquid, low freezing point, is a polar molecule.
