Why Does the Ocean Sometimes Look Green?

The ocean can look green because sometimes the water has tiny green things in it, like algae or little sea plants. When sunlight hits them, they make the whole ocean look green, like a big green pond! It's kind of like when you add food coloring to your bathwater; everything turns colored.
