The fact that water's solid phase is less dense than its liquid phase is important for aquatic organisms because it means that they will be able to live below the ice. This is evident when a lake freezes over to a certain extent while the fish and aquatic life is fine until the ice melts.
It is an arm of ecology that studies microscopic organisms in aquifers, reservoirs, wells, other drinking water systems, and fresh water biomes to determine that the waters are free of polluting microorganisms.
It all depends on the liquid, like waters boiling point is diffent then something like Mercury
Solid waste: metals, building materials, glass, ceramics, plastics, papers, etc. Liquid waste: polluted waters from industry and domestic use, etc.
The solid state of water is less dense than its liquid state, which is why ice floats on water. The solid state of nearly all other substances is more dense than the liquid state and sinks in the liquid state.
For example a solid from a liquid; evaporation of water from sea waters give salt.
because it has oxygen and reused by other aquatic organisms
They house aquatic animals and the water is beautiful.
They live in waters.

because it is bad
they tend to be more abundant to warmer waters
I suppose that the acidic aquatic environments (including ocean waters) are more common and dangerous.
Narwhals migrate to the shallower of the Arctic waters in summer. There, the aquatic fare is plenteous and easy to chase. But the pickings are fewer with the end of the summer season. So narwhals migrate to the deeper of the Arctic waters in winter. There, the aquatic fare requires deep diving in order to be caught and eaten.

The four main factors that affect aquatic ecosystems are waters depth, temperature, flow, and amount of dissolved nutrients.
This is the pollution of soils and waters with salt. In water salt pollution changes the osmotic pressure of aquatic organisms (leading to death) and in soil it changes the osmotic pressure for plant roots (death again) and destroys the ionic soil structures.
A dugong is an aquatic mammal that is distinguished from the manatees by its forked tail. It is found in warm coastal waters from East Africa to Australia.
