Amoebas are zooflagellates and live in fresh water. There are about 15 phyla of these animal like protists and many are fresh water types.
Zooflagellates may live in lakes and streams where they feed on bacteria and algae, helping to maintain the ecosystem's balance. They play an essential role in nutrient cycles and are an important food source for larger organisms.
Not in lakes but they may live close to lakes.
They die and may mutate this is very, very rare
You may be thinking of 'steams' but the two words don't really rhyme.
Zooflagellates differ from other protozoans because they are unicellular and may live on their own or on a host as a parasite. They have long bodies with one large nucleus. They reproduce by binary fission.
Sometimes yes and sometimes no. If the level of the water goes up it may effect your place of living. Think a lot of times before deciding to live next to lakes and rivers. Hope This Helped! :D
Because the dry land they may live on now might had been a former lake or ocean
It is not known weather it may venture into salt water, but it is routinely caught in freshwater rivers and lakes
An example of a flagellated protozoan is Trypanosoma, which causes sleeping sickness in humans and animals. These parasites have a whip-like tail (flagellum) that helps them move through fluid environments.
Snowy owls live in the grasslands, the tundra region and in areas with frozen lakes as well. Snowy owls are found in the circumpolar Arctic, but may irrupt far south in severe winters in numbers.
