Characteristics: 1. _Microscopic size_: Typically ranging from 0.2 to 5 millimeters in length. 2. _Drifting lifestyle_: Zooplankton are mostly unable to swim against currents and drift with the water. 3. _Animalian nature_: Zooplankton are heterotrophic, meaning they consume other organisms or organic matter for energy. 4. _Diverse group_: Includes various species, such as crustaceans (e.g., copepods, krill), mollusks, fish larvae, and protozoa. or aquatic ecosystems?
