Difference between ecosystems
Fresh water, Brackish water, and Salt water
- Mixture of salt and freshwater
- A salinity of about .05% - .3%
- Usually happens when rivers meet the sea or lakes are fed by saltwater estuaries
- Can be dangerous to the environment because they can kill native species
- Certain lakes, estuaries, and mangroves
Organisms that live there are specially adapted to the salinity of the water:
- On average, seawater in the world's oceans has a salinity of about 3.5% (35 g/L, or 599 mM). This means that every kilogram (roughly one litre by volume) of seawater has approximately 35 grams (1.2 oz) of dissolved salts.
- Salt water has an average density of 1.025 g/ml, but the density increases as you go deeper.
- Salt water is unsuitable for human consumption
- Salt water in the oceans is home to millions of species of life.
- Salt water is denser than fresh water
- Seas, and Oceans
Here are just some of the animals and plants that live there:
