What might you see if you looked at pond water under a microscope?

You might see bacteria which belongs to the Kingdom Monera. You likely will see tiny animals like rotifers which belong to the Kingdom Animalia and of course, there are the Protozoans and Algae which belong to the Kingdom Protista. The algae are single celled plant-like protists and the protozoans are single celled animal-like protists. Remember, the Protists are neither animals or plants but in a Kingdom of their own.
