Define Brackish zone. |
Area where fresh & salt water meet - salinity between 0.5 & 30
|
Define osmoregulators. |
Actively central salt concentrations despite salt concentrations in their environment.
|
Describe water stratification in the Baltic Sea. |
Saltwater at the bottom, freshwater on top.
|

Speed it can swim & how long it can maintain that speed.
|
What is sound? |
Long body of water between island & mainland.
|
Organism which can tolerate saltwater, using heir special tongue glands to remove excess salt. |
Crocodiles
|
What is water eutrophication and how does it negatively affect ecosystems? |
High concentration of phosphates and nitrates decreasing O2
|
Oxygen's solubilty in water ____________ water temperature _________ |
decreases , increases
|
________________ recycle energy. |
Bacteria
|
Define poikilotherms. |

|
Define Nekton. |
The aggreate of actively swimming equatic organisms in a body of water.
|
Define glide habitat. |
Non - turbulent, moderate - velocity , low gradient macrohabitat with a wide channel and no thalweg
|
Eutrophication promotes excess growth of _____________ |
Algae
|
This type of water is hostile to the growth of most terrestriaal plant species and could be damaging to the enviornment. |
Brackish
|
Where a river meets a sea. |
Estuary
|
How do dams impinge on anadromous and catadromous species? |
Stopping them from returning to marine or fresh
|
This organism can tolerate marine environments by increasing its urea production and retention, and by remaining slightly hyperosmatic within urea and sodium flux. |
Crab - eating frog
|
Why does water stratification occur and what does it lead to? |
Salt water is denser than fresh ; leads to decreased O2 concentration.
|
