    Question

    How do green plants in the sea help fish to respire?

    A.

    They give out oxygen

    B.

    They give out carbon dioxide

    C.

    They give out oxygen and carbon dioxide simultaneously

    D.

    They take oxygen and give out carbon dioxide

    Correct option is A

    The correct answer is (a) They give out oxygen.
    · Green plants in the sea (such as phytoplankton and algae) perform photosynthesis, a process in which they take in carbon dioxide and release oxygen.
    · This oxygen is dissolved in the water and helps fish and other aquatic organisms to respire.
    Information Booster:
    · Photosynthesis is crucial for maintaining the oxygen levels in aquatic ecosystems, which in turn supports the respiration of marine life.
