Question

type of microorganisms are found in the pond water

Answer 1

Pond water contains a number of arthropods such as copepods, water fleas and ostracods (crustaceans). These types of microorganisms are visible to the naked eye (with the largest specimen exceeding 3 millimeters in length), and can therefore be seen without the use of a microscope.

Some of the other organisms in this group include among others; water mites, mosquito larvae, water bears (tardigrades) water shrimp and other larger crustaceans like the water louse. Depending on the type of arthropod, some will be found on the surface (most insects) while others can only survive in the water as is the case with most crustaceans.

Answer 2

Microorganisms are simple, single celled organisms that can be found all around the world. They are largely composed of the members of the plant kingdom, fungi, bacteria and protozoa. As such, they are only visible under the microscope.
However, as is the case with some species, microorganisms may cluster together in large numbers (colonies), which allows them to be visible to the naked eye or when using a magnifying glass.
Typically, pond water will contain a variety of microorganisms with a drop of the water carrying thousands of these single celled organisms. Some of the most common living in pond water include;
