Answer 2

Explanation:

Visible radiation, or light, from the Sun is important to the world's ocean systems for several reasons. It provides the energy necessary for ocean currents and wind-driven waves. Conversion of some of that energy into heat helps form the thin layer of warm water near the ocean's surface that supports the majority of marine life. Most significantly, the transmission of light in sea water is essential to the productivity of the oceans.
