All protists are eukaryotic (have a nucleus), most live in water. They are the "ancestor organisms" because they were the first organisms ever to exist.
Protists are simply organisms that don't fit into any of the other kingdoms.
The great diversity of form, habitat, mode of nutrition, and life history exhibited by eukaryotes suggests they evolved several times from various groups of prokaryotes. This makes the Protista a polyphyletic group. Eukaryotes are generally larger, have a variety of membrane-bound organelles, greater internal complexity than prokaryotic cells, and has a secialized method of cell division (meiosis) that is a prelude to true sexual reproduction. Protists might be viewed as a group from which the other eukaryotic kingdoms evolved.
they eat by photosynthesis or by other organisms......

The protists that are like animals feed on other protozoa, amoebas, and algae.
No, protozoans are a type of animal-like protists. Protozoans are consumers that can live in water, soil, or other organisms. While these organisms do not resemble animals, they are called animal-like because they are consumers and they share some characteristics with animals. Other types of protists are plantlike and fungus-like protists.

Many protists do not leave fossils:)
The only organisms that like to eat protists that I have heard of are other species of protists and people fond of Japanese cooking.
Amoeba eats other organisms and smaller protists

Algae and other tiny organisms that live in water are classified as plankton. Plankton are important members of aquatic ecosystems, serving as a food source for larger organisms and playing a role in nutrient cycling.
