Question

What organism i could find in a Hay Infusion set-up? I need names please. We made a Hay Infusion setup and we saw the results somethings were moving but we don't know what are those, our teacher in our biology class gave us an homework this weekend, we must find the name of that organism.. thank you guys in advance

Answer 1

When I did a hay infusion, the most common easily observed organism was Paramecium aurelia.

There was also some Vorticella attached to individual plant fibers.

Answer 2

You're most likely to see Paramecium and Euglena.  Both are motile, slipper-shaped protozoa that are very common.
