Rainbow trout, plankton, Largemouth Bass, Freshwater eel, some types of frogs, crabs, shrimp, some ants, some dogs, and some pie.
consumers are organisms that eat other organisms. Depends on what level consumer it is ;).
Earthquakes generally have minimal effects on a freshwater ecosystem. Because fault lines do not tend to go through a freshwater ecosystem, the quakes cannot to harm directly to the organisms. Some damage that could be a result of a quake would be trees falling down, some organisms falling down and loosing their balance, ect. As you can see, it is not exactly a bad problems all the freshwater organisms have to worry about. And naturally, it would depend on where the ecosystem is. But overall, the earthquake really doesn't play a factor into the ecosystem as a whole.
phytoplankton
It is the farming of saltwater and freshwater organisms
Acquaculture
The extinction rates of terrestrial and freshwater organisms varies per location. This is largely dependent on other growing and declining populations.
Plankton
Ecology addresses the relationships between organisms and with their environment. Freshwater ecology studies those relationships in freshwater (non-salty water) environments.
A freshwater organism is any celled living creature that can only survive in fresh(non-salted) water.
Gills
some are freshwater some are saltwater
look up bacillarophyta on wiki. these were some of the first organisms to live on earth.
