What are the three Monotremes alive today?

The echidnas are sometimes treated as only two species and sometimes treated as 4, 5, or 8 depending on the authority.  Some consider Zaglossus bartoni and Z. bubuensis as subspecies of Z. bruijni.  Likewise, there are variants of Tachyglossus that have also granted species status by some authorities: T. lawesi, T. typicus, and T. setosus.\n\nThe three monotremes are the platypus: Ornithorhynchus anatinus, and the two species of echidna: Tachyglossus aculeata and Zaglossus bruijni. If 5 species are recognzied, the additional two are Zaglossus bartoni and Zaglossus bubuensis.

1) phototropism, I'm down with that...\n\nHow 'bout these? 2) evolution, 3) plate tectonics. That's got us up to 3. Still looking for two more.

This is one of the biggest unknowns left for modern scientists to answer. Archea is such a black box. We can't even detect these guys well enough to definitively answer the question if there is a significant presence of Archea in our ecosystems -- internal or external environments -- let alone if these ancient bugs are pathogenic in any way.\n\nI'm of the camp that believes that there will probably be a lot of determined in the future that will make it much more apparent the answer to this question.\n\nBy the way, great question.

Amoeba are among the largest single celled organisms, far larger than any bacteria.  Some amoeba are large enough to be seen without needing a microscope!\n\nBacteria are the smallest living things and mycoplasms are the smallest living bacteria (known as nanobacteria).\n\nIf by creatures you mean animals, then the smallest depends a bit on your definition of "small".  The shortest is probably little Trichoplax adhaerens, which looks a bit like a hairy, multi-cellular amoeba.\n\nThe smallest animal in terms of number of cells is probably some kind of Mesozoa, a set of worms famous for being very short and only a few cells across, so much thinner than Tricoplax and less massive.\n\nThe smallest vertebrate is a species of fish that was just discovered recently, though I forget the name of it, sorry.  :-)\n\nIt's recently been discovered that a few single-celled organisms are, in fact, evolved from animals.  If you would count these as animals, they would be the smallest animals, though that would be merely a technicality.\n\nAll of this applies only to adult forms, of course.  We're all very very small to begin with!

I DONT THINK THAT WE R  ALONE . WE HAVE SEEN A FEW SIGNS OF XTRA TERRESTRIAL LIFE AND IT  IS POSSIBLE THAT THERE ARE OTHER LIVING ORGANISMS INHABITED PLANETS

The first three are correct.  I am having difficult finding an organism that is not somehow connected to an energy source.
