Temperature and density share an inverse relationship. As temperature increases, the space between water molecules increases—also known as density, which therefore decreases. If the temperature of water decreases its density increases, but only to a point. At a temperature of 4°C pure water reaches its maximum or peak density, cooled further it expands and becomes less dense than the surrounding water which is why when water freezes at 0°C it floats.
Salinity and density share a positive relationship. As density increases, the amount of salts in the water—also known as salinity, increases. Various events can contribute to change in the density of seawater.
Salinity can decrease from the melting of polar ice or increase from the freezing of polar ice. Evaporation increases salinity and density while the addition of freshwater decreases salinity and density.

Freshwater means low salt content. The zones namely Standing which is compose of ponds and lakes and has littoral zone which algae,floating aquatic plants and clams can be found. Next is limnetic zone and has plankton. Next is Flowing includes streams and rivers and in there resides catfish and carp. For sea water it has Marine which has aphotic zone where anemones,arrow worm and angler fish resides.Another, coastal zone compose of coral reefs and mangrove and lastly the intertidal zone with small critters.
