Can someone help me with this please?

Photosynthesis uses solar energy, carbon dioxide, and water to release oxygen and to produce energy-storing sugar molecules. ... The process of photosynthesis can be represented by an equation, wherein carbon dioxide and water produce sugar and oxygen using energy from sunlight.

Wind produces the energy, initial motion and direction of the surface current of the ocean.An ocean current is a seasonal directed movement of seawater.
Surface ocean currents are primarily affected by wind. The Gulf Stream is example of it. Trade winds push water along the top of the ocean and this results in formation of surface currents.
