    A) Nektons

    B) Zooplanktons

    C) Phytoplanktons

    D) Benthos

    Correct Answer: B

    Solution :

    Zooplankton are heterotrophic (sometimes detritivorous) plankton. Plankton are organisms drifting in oceans, seas, and bodies of fresh water. The word "zooplankton" is derived from the Greek zoon meaning "animal" and planktos meaning "wanderer" or "drifter". Individual zooplankton are usually microscopic, but some (such as jellyfish) are larger and visible with the naked eye.
