Yes, they can.
the Euglena has a better chance of survival because it can capture prey.
It should be fairly easy to find paramecia in freshwater ponds, and basically any other mass of fresh water, especialy those with lots of water plants in them, Euglena is just the group of protists they are in. You can find amoebas in exactly the same kind of places, but the amoeba is slightly more sensitive to pollution, so you are less likely to find it in polluted areas.
The parameceum can reproduce asexually and sexuallly while the other 2 can only do it asexually. they have diifferent structures (Google the images) and the euglena has a flagellum while the paramecium has cilia and they eat differently. the amoeba works its pseodopotium around its food and digests it in the food vacuale the paremecium uses the cilia to get a water current going and the food gets sucked in and the euglena uses photosynethesis by using its stigma to indicate areas of light and if not then it will just get food like the other 2
Euglena (and other protists) are Eukaryotic
Amoeba is animal-like because they can not do photosynthesis which other plant-like protists can do. Amoeba are protozoans. Amoeba hunt for their food. They eat bacteria, smaller protozoans and other smaller organisms.
The most obvious difference between an amoeba and a paramecium or euglena is that the amoeba has no overall shape, and the entire cell changes its shape as the amoeba moves. The paramecium and the euglena both have definite shapes which they do not alter. The amoeba can engulf food particles at any point on its own cell membrane, but the paramedium has an oral groove which is where it ingests food particles. And the euglena also has a chloroplast, unlike the other two (or any other protozoan).

Amoebae are heterotrophic, meaning they must eat other organisms to survive.

Some protists include algae, diatoms, paramecium, rotifers, flagellates, amoeba, and giardia. Other protists include trichomonadida, euglena, trichonympha, ceratium, and dinoflagellates.

"The eye spot is a photo receptor. It alerts the Euglena to the presence of light. The chloroplast uses light to carry on photosynthesis. While the Euglena is in the presence of light it is making food. The Euglena also can eat food like other Protists if there is no light." quoted by ATP-Man (http://answers.yahoo.com/question/index?qid=20080114172048AAK4szq)
If they CAN survive without oxygen, they are called facultative anaerobes. In other words, these can survive with or without oxygen.If they CAN ONLY survive if there is no oxygen, they are callled obligate anaerobes. In other words, these can only survive if there is no oxygen.
It's a strict autotroph, unlike other Euglena species.
Euglena (and other protists) are Eukaryotic
Amoeba eats other organisms and smaller protists
Anaerobic animals (and other substances) survive without oxygen.
