    Ok, so I have a few questions I'm not sure about, can anyone help?

    1) Suggest 2 advantages to the phytoplankton of being concentrated just below the sea surface.
    - i put it enables them to absorb sunlight easily for photosynthesis, but cannt think of another one

    2) What does gCm-2 stand for when expressing primary productivity. In full.

    Thankyouu

    1)
    - good position to capture sunlight
    - wins competition with plants growing on the sea bed e.g. seaweed

    2) grams of carbon per metre squared
