  1. How do you think depth affects the colors of objects a diver can see at a depth of 5 meters into the euphotic zone compared to a depth of 30 meters?
  2. Coral and algae need light in order for photosynthesis to take place. How do depth and the availability of light contribute to how these organisms are distributed on the ocean floor?
