Which organism is commonly classified as macroplankton?

Explanation:
Macroplankton are the largest plankton, visible without a microscope, that drift with the water’s movement. Jellyfish fit this category because many adult medusae are centimeters to decimeters in size and float or drift in the open ocean, only weakly swimming against currents. This size places them in the macroplankton group. In contrast, diatoms are tiny phytoplankton cells, typically only micrometers to a few tenths of a millimeter in size. Copepods are small crustaceans usually a few millimeters long, falling into micro- to mesoplankton. Bacteria are even smaller, known as nanoplankton.
