Definition: Hemiplankton is a group of organisms that primarily live in water bodies, such as rivers or lakes. These organisms are characterized by their ability to form complex structures and have specialized functions within aquatic environments. Hemiplanktons typically include bacteria, algae, protozoa, and certain types of invertebrates like crabs and fish. In contrast to other forms of planktonic life, hemiplanktons do not undergo photosynthetic processes or use sunlight for energy production. Instead
